[Libreoffice-bugs] [Bug 153985] Horrible performance scrolling up with PgUp when Automatic Spell Checking is on [kf5 (cairo+xcb), X11]
https://bugs.documentfoundation.org/show_bug.cgi?id=153985 --- Comment #15 from Dan Dascalescu --- I've upgraded to 7.6.2.1. Scrolling is much slower when running LibreCalc as root, even with Automatic Spell Checking off. Graphics Output settings are the same for both my user and root, all on: * use hardware acceleration * use anti-aliasing ``` $ sudo libreoffice7.6 javaldx: Could not find a Java Runtime Environment! Warning: failed to read path from javaldx ** (soffice:272859): WARNING **: 14:56:45.260: AT-SPI: Could not obtain desktop path or name ** (soffice:272859): WARNING **: 14:56:45.264: atk-bridge: GetRegisteredEvents returned message with unknown signature ** (soffice:272859): WARNING **: 14:56:45.264: atk-bridge: get_device_events_reply: unknown signature ``` When running as my user, scrolling is fast and: - LO can't find a Java runtime either - those other two warnings don't appear. Instead I see: ``` $ libreoffice7.6 javaldx: Could not find a Java Runtime Environment! Warning: failed to read path from javaldx qt.qpa.wayland: Wayland does not support QWindow::requestActivate() ``` OpenCL is not used by either. I don't know what other difference in settings to look for. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=153985 --- Comment #14 from Dan Dascalescu --- I see much slower scrolling if running the same LibreCalc as root on the same OS, than if I run it as my regular user.

https://bugs.documentfoundation.org/show_bug.cgi?id=153985 --- Comment #13 from Dan Dascalescu --- I've done more testing. With 7.5.2.2 on KDE Wayland, I see fast scrolling, getting slightly slower after scrolling up a few thousand rows, but nothing to complain about. Scrolling again from the last row towards the top while keeping the document open is noticeably faster (perhaps some caching happens?)

https://bugs.documentfoundation.org/show_bug.cgi?id=153985 --- Comment #11 from Michael Meeks --- Fun - so, there's nothing obvious from the patch there - it should save time and space. What would be useful would be running perf on it to see where the bottleneck is I think; and/or running a dbgutil build with: SAL_LOG="+INFO.vcl.schedule" And then seeing what it produces while you scroll; I expect that we're doing too much spell-checking work vs. rendering work for some reason - that is (no doubt) related to some quirk of how the events are processed. -- You are receiving this mail because: You are the assignee for the bug.

Reviewed-on: https://gerrit.libreoffice.org/c/core/+/104706 Before the commit, the view can choke up a little shortly after starting the scroll, but goes back to frequently refreshing. After the commit, same as in the video: very infrequent refreshing, all the way to the top. Looking at the commit, I figured turning off Tools > Automatic Spell Checking fixes the issue. Michael, can you please have a look? Dan, can you confirm that: - it only happens with kf5 (cairo+xcb) - turning Automatic Spell Checking makes it smoother Referenced Bugs: https://bugs.documentfoundation.org/show_bug.cgi?id=96000 [Bug 96000] [META] Spelling and grammar checking bugs and enhancements https://bugs.documentfoundation.org/show_bug.cgi?id=102495 [Bug 102495] [META] KDE VCL backend bugs and enhancements -- You are receiving this mail because: You are the assignee for the bug.

Tested on Ubuntu 20.04 with GNOME 3.36.8 + Wayland with: Version: 7.5.2.2 (X86_64) / LibreOffice Community Build ID: 53bb9681a964705cf672590721dbc85eb4d0c3a2 I made sure to zoom out a bit so columns A to K were visible. - With gtk3 VCL, no slowdown (although keeps scrolling for a bit after releasing the key) - With kf5 (cairo+xcb) VCL (window is GType:MetaWindowXwayland, so goes through Xwayland), same slowdown as in video, the interface sometimes unresponsive for a few seconds after stopping the scroll. The scroll takes the same time to get to the top, but it's the view that does not refresh frequently, hence the large jumps. - With kf5 (cairo+wayland) VCL (window GType:MetaWindowWayland, so Wayland native), no slowdown. If you use Wayland, you can see if using native Wayland works better by launching LibreOffice with extra variables from the command line, for example: SAL_USE_VCLPLUGIN=kf5 QT_QPA_PLATFORM=wayland libreoffice7.5 Referenced Bugs: https://bugs.documentfoundation.org/show_bug.cgi?id=146014 [Bug 146014] [META] Poor Scrolling Performance -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=153985 --- Comment #5 from Dan Dascalescu --- Will try to bisect when I have some time, but for now I'm happy to report that on Fedora 37 KDE Wayland, scrolling is super fast in Calc 7.4.6.2 (albeit on a ThinkPad P1 Gen 5, rather than my old X1C Gen 7, but I strongly suspect the hardware is not the culprit).
