https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #54 from Tomaz Vajngerl --- It's a known issue that rendering of (bigger) images is not fast in LO in all of the backends for many reasons (swap-in / swap-out, separate alpha channels in LO, non-optimized scaling algorithm which don't use SSE or AVX or don't use native surface scaling, ...). This particular issue was that gtk3 was rendering even slower and was solved. I would really suggest to open a new bug about this (all the old talk is distracting and non-relevant) and make sure that it really is gtk3 only that has the problem, otherwise there are other bugs that already cover this. I wonder if we should limit the time how long a solved bug can be reopened. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #53 from Clemens Eisserer --- I did some digging, and although I am far from a solution (even a stop-gap one), these are my findings: - the gtk3 vcl plugin seems to render to a software surface, toms of cycles are wasted scaling the input bitmap over and over in pixman library routines: SvpSalGraphics::drawAlphaBitmap -> composite_boxes -> general_composite_rect - the gtk and x11 vcl plugins seem to render to a native surface (which is usually a lot better), however both are doing stupid stuff (extracting the alpha values again and again) - therefore reading back image data from the XServer using XGetImage (no-go for good performance): drawinglayer::impBufferDevice::paint -> AlphaMask::AlphaMask -> Bitmap::Convert -> ... -> X11SalBitmap::ImplCreateDIB -> XGetImage Maybe I can find howto switch gtk3 to using a native XRender surface (these days XRender is rather capable, layered above OpenGL (glamor) anyway) and then work on the second issue... -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #49 from Clemens Eisserer --- I've experienced the slowdown described in this bug report for many real-world documents and it always made me suffer editing or reading such documents. I tested this (PNG_one.odt) on two systems (same SSD swapped - so no software differences): 1. Intel Core i5 640M (laptop, 1st gen Intel Core): Very pronounced stuttering (despite only 1280x800 screen), editing or working with such documenbts is a real pain: https://youtu.be/V8Sr_OHeyyI 2. AMD Kaveri A8-7650k @ 4Ghz: Scrolling is ok even on 1920x1280 screen, although it is slower while the image is visible. Good enough to edit the document. On both systems tested I see a lot of CPU cycles spent in Xorg in fbBltOne, which is some kind of software fallback. The AMD system seems to be faster when reading VRAM into system memory, so the fallback is less noticeable. I'll try to investigate further... -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

I use touchpad scrolling all the time, so it's like hell to me to scroll through images with it. In the attached video, I start scrolling by dragging the scrollbar, then I scroll using a mouse scrolling wheel, at the end I use the touchpad 2-finger-scrolling gesture.

While I was proofreading a draft for a paper I notied a slowdown again (MSO DOC 97 file, some embedded graphics), and this time it was with libreoffice-bin (the official binary for Linux in Gentoo v4.4.4.2) on an E-350 APU (somewhat different HW but similar driver stack). Here OpenGL was off, just use HW accel and anti aliasing = 1. (force OpenGL = 0) The slowdown was quite hard.

https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #29 from just-me --- Sorry for the long silence but this is a life-suffocating 24/7 job here. I confirm for LibO 5.0.2.2 - I recently put some thermogravimetric measurements together and especially the 256 colour PNG files (the true colour not so much) result in jerky and slow scrolling / slow response from LibO, even more when zoomed in. As soon as they are off screen scrolling etc. goes back to normal. The slowdown is not as intense as earlier - the system doesn't feel "frozen" but a slowdown is still noticeable. Tested on 1200x1920x24bpp (Pivot) screen; mesa 10.6.8 (radeonsi), libdrm 2.4.64, kernel 4.2.3 and xorg-server 1.17.2 with xf86-video-ati 7.5.0 (glamor = 1). The libpng slots are 1.2.52; 1.5.21 and 1.6.18. The PNG images are of size about 2000 x ~ 1370 pixels, DIN A4 page size in LibO writer. I also noticed some of that during a scan project similar to the one mentioned above by Adrian Maire (since the public office insisted on a PDF document and said they could not print PNG files (sic!)). I still have no clue if this is related to an issue directly with LibO or if the culprit lies in the interaction of LibO with the free AMD driver stack. -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #26 from just-me --- Update: Few problems with PNG noted. But SVG, 2 page-wide images per page causes extreme slowdowns again. The SVGs are b/w (transparent) only, just lines (NMR spectra, looks a bit like a garden fence) and some font text. They do have several vertex points, though (SVG file size 80 ... 200 KB). Scrolling and text editing becomes unbearable often. As soon as these are off screen things become better. Messing with the memory reserved per graphic object settings didn't seem to help (yet). Also closing browsers (might block 2d accel resources??) on other virtual desktops didn't change things. Any suggestions for possible traces to run during such a work?

https://bugs.documentfoundation.org/show_bug.cgi?id=87485 --- Comment #25 from just-me --- I am working about daily with LibO and the problem... well, sometimes seems to persist. Or it is not so expressed anymore. I sometimes get a slowdown, so typing / erasing text is delayed and scrolling is jerky. Not as expressed as before. But I noticed it also happens with SVG files, too. (And SVG handling in LibO is also a different topic.) Generally I'd say things have improved, though I can't really trace if those improvements were inherited from LibO updates or updates in the AMD free driver stack. Or even a libpng update meanwhile. (Besides I am now on 8 GB memory but that shouldn't change things that much, I hope.) Still, most JPEGs were nice but low bpp colour depth PNGs were strangely a problem, and now some SVGs. Hence my original suspicion that LibO was handling things somehow differently with PNGs and full colour JPEGs. Valgrind didn't show overly much in the log (without -v there was basically 0 error and no leaks as a result). I can attach a -v log if you want. I am a bit confused trying to reproduce things. For one it seems to have improved, but sometimes, in the middle of writing I get a few slowdowns here and there. On the other hand these are then kind of uncontrolled environments, means, I also do have a lot of PDFs open in okular (KDE's pdf reader frontend), often a browser with several tabs and music running. The browser and pdfs could be a resource hog so it's a real world test but not suitable for proper reconstruction of bug behaviour. :/ I'll still have a lot of pictures to insert into text and will also - as far as time allows - try to change colour depth, image format and picture size and see if I find something again that show this behaviour again. In the light of improvements it would be interesting to know if somebody touched LibO's code that handles images / rendering. And yes, #78529 #80659 seem to describe a very similar (the same?) problem. -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

--- Comment #9 from just-me ---
Hello
Sorry for my slow response, but science can be an extreme time hogger.
On the document: Yes, of course. I just recode the image to JPEG and embed the
jpeg instead of a PNG in a fresh or the old file and things get better.
On the machine(s): Yes. Of course I should have done that earlier. But it was
partially up to 16 h work some days so I couldn't even look straight anymore.
Current is 5350 APU, latest mesa etc. and LibO 4.3.5.2 (compiled one).
I could check this on
* VIA C7 (x86_32, Gentoo, openchrome on CN700) with some binary release of LibO
* AMD Geode LX 800 (x86_32, Gentoo, xf86-video-geode on the Geode GPU) with
some binary release of LibO
* AMD E-350 (amd64, Gentoo, free stack on E-350 GPU part) with latest and
greatest unstable LibO from portage ("self" compiled but
* AMD Athlon II X4 (amd64, Gentoo, free stack on a HD 5670) with latest and
greatest unstable LibO ...
* AMD Athlon II X4 (same box, Windows XP 32 bit, AMD Catalyst blob) binary
Windows release of LibO
* some old laptop I got rented (intel P3 or P4 era?) with. XP 32 but iirc also
some AMD/ATI mobile GPU and blob driver, binary LibO
* an ancient ARM build of... oh, wait, that was still Openoffice :) on my semi
defunct AI Touchbook
* and some ancient boxes and loose mainboards without an OS currently. :)
Honestly I wonder what causes the behaviour. I suspect a mix of GPU driver on
the Kabini and LibO doing something different with the PNG to send it to the
screen than it does with the JPEG.
Still, other programs display them without visible problems (I might try to
install abiword or calligra to check with that)
I found that some binary applications do use emul-linux-x86-x (these are
Gentoo's 32 bit precompiled libs for compatibility in 64 bit systems).
However, they contain libs from Gentoo stable (maybe not as old as Debian
stable, but you get the point). Thus e.g. the emul-linux-x86-opengl contains a
mesa that is not even aware of the existance of Southern/Sea Islands GPUs used
in the Kabini chips. Of course rendering then is a horror. But then,
LibreOffice doesn't make use of them (32 bit compat. libs), does it?
If there is any trace or something I should run during runtime while scrolling,
just tell me what to do.
MS-Windows test: Sorry, I only have DOS/W3.11 rotting somewhere, DOS/W9x and XP
but the XP is not on the Kabini. I mean, if it was as easy with licensing and
installation as a Linux distribution I might just have tossed it on some
external HDD/flash and booted it via USB from the same machine. But even then
the GPU driver would have been different (among a lot of other things, of
course).
I'll test tomorrow on some of the boxes with the problematic files and see what
happens.

Do you have a (separate) sample document for that? Also: Do you have a separate system on which you can test? It would be great to confirm whether you see the problem on a separate machine/OS. You also mentioned that you have a Windows machine (or dual boot?) that would be a great additional test, especially if it's on the same hardware. -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

"Same" image as JPEG (same resol.) does not lead to visible problems. Does Libreoffice (Writer) use other techniques to bring the images to display? Or is the culprit hidden somewhere else? (GPU driver?) Always: As soon as the image is off screen scrolling/response is back to normal. I also have a second file with different images but bringing up the same problem. (PNG vs. JPEG) Also there are PNG files which do not slow down writer (at least not noticeably), regardless if they are true colour, 8 bit color or greyshade. Sadly I have a lot of these files and must put a lot of them in long documents... -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=87485 --- Comment #3 from just-me --- Sorry for the long pause in delivery. But I was totally stressed throughout the "holiday" break with writing / checking a publication. Not even time for family. I'll put something up soon. Just give me a few moments since it is from an unpublished (yet) scientific paper. Could it also be related to some video acceleration problem? (note me if you need HW details) Even typing became extremely slow. I have other parts of the sci.paper (different ODT file) with pictures where nothing unusual happens. Also, if the picture is totally off screen (and thus not rendered) things speed back up to normal. By the way, opening the images (as PNG) in e.g. kolourpaint or gwenview does not slow down. And even higher res. pictures are scrollable (in kolourpaint). I tried to see if it was jsut related to colour depth but that did not seem to be the case. I'll try to prepare a file and another one where the issues does not occur (e.g. this PNG vs. the same as JPEG). And happy new year everyone. PS: I also updated libreoffice and xorg-server over the last night (Gentoo compiling, you know...), have to see if something changed. -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=87485 --- Comment #2 from renn0xt...@laposte.net --- very same problem here with kubuntu 14.04 (32 bit) and libreoffice 4.7.2: 1) Design a diagramm with 2 boxes in libreoffice draw 2) Export it one time 3) See how crap the default parameters are *** this bug is already reported 4) Export it a second time in 600 pixel/cm to have decent resolution 5) Obtain the picture (it is only 600 kB) 6) Import it into a 8 pages long document 7) Crop it because Draw can not easily export only the part you want 8) Buy Windows and Microsoft Office to type the rest of your document, because your system is now unresponsive Making sample files with a few pages of text, a few pngs etc, is PART OF THE NORMAL TESTING CAMPAIGN that should occur BEFORE EACH RELEASE.. Also I am convinced that such files were already produced by the developer/tester who gave the go for release (were'nt they?) In case you need it, just ask them ;) Best regards... -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

I wasn't able to reproduce it with LiO 4.3.5.2 under Win8 moreover exactly define what to you do to "embed" the file (from "insert/image" menu of copying and paste it from image editor) and how the scrolling issue happens (using arrowkeys, mousewheel or both). also consider upgrading to 4.3.5 set status to NEEDINFO. revert it to UNCONFIRMED when you provide these infos -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
