https://bugs.documentfoundation.org/show_bug.cgi?id=145988 --- Comment #85 from Patrick Luby --- My patch passed all unit tests after only enabling my fix for macOS. My fix should be in tomorrow's (21 September 2023) nightly master build. Based on the unit tests, I am assuming that this bug only occurred on macOS. But if anyone sees this bug on Windows or Linux, please reopen the bug and I'll add my fix for that platform. -- You are receiving this mail because: You are the assignee for the bug.

While experimenting, I found that when a window moves to another screen, macOS may change the pixel format of the window's CAMetalLayer. Skia forces the pixelFormat to RGBA when it creates the CAMetalLayer, so I added code to force it to RGBA when the screen has changed as well. Would anyone be willing to try the latest nightly build and see if there is any change in the thumbnail image colors or the Help > About dialog image colors? If there is no change in colors, can you run the nightly build from the Terminal using the following command and then paste any output in the Terminal that you see?

What jumped out at me is that the following line for the Radeon Pro 560 GPU: Framebuffer Depth: 30-Bit Colour (ARGB2101010) On both my machines, both the built-in monitor and my external non-retina monitor connected via HDMI are 32-bit color (ARGB888) and Skia, internally uses the same pixel format. So, my current theory is mismatched pixel format between what Skia wants to use and what the Radeon Pro 560 wants to use.

The yellow document previews in Start Center + Impress Template selection are persisting as is the yellow image in About Window. The issue looks identical to the screenshots I posted back in 2021 except I am now using dark mode, which does not change anything in regards to the issue.

https://bugs.documentfoundation.org/show_bug.cgi?id=145988 --- Comment #64 from Patrick Luby --- My current theory is still that this bug is caused by certain GPUs are not able to handle the combining of 24-bit opaque and 8-bit alpha bitmaps. Apple provides some ways to test the feature set of a particular GPU, so I am curious if those of you who experience this bug have a particular set of GPU features or limitations that is different from other machines. Can anyone who experiences this bug upload a screenshot using the following?: 1. Select the Apple > About This Mac menu item 2. In the window that appears, click the System Report button 3. In the window that appears, select Graphics/Displays in the sidebar 4. Take a screen snapshot of the window by pressing Command-Shift-5 and clicking on the window. 5. Upload the screen snapshot from your Desktop as an attachment I don't see this bug on either of my Intel or Silicon MacBook Pros but I have uploaded screen snapshots for comparison in attachment 184668 and attachment 184669. -- You are receiving this mail because: You are the assignee for the bug.

So, I think the next place for me to investigate is the code where Skia copies its bitmap pixels to the screen. >From what I can see, Skia creates a macOS CAMetalLayer to each LibreOffice NSView and draws to the CAMetalLayer. macOS then copies the CAMetalLayer to the screen in -[NSWindow displayIfNeeded] so maybe the CAMetalLayer has an unexpected pixel format or colorspace Skia does not know how to convert to.

I found that, in the Start Center's document thumbnails, the thumbnails are bitmap images created from the .png images created when you last saved the document. Also, I found that there is no clearing before drawing the thumbnail bitmap. Instead, the thumbnail image contains all of the white (yellow with the bug) pixels that are drawn.

I also don’t think the issue is > limited to images, even the thumbnails in the start center have their white > color turned into yellow. You have a good point about the document thumbnails in the Start Center so I traced how they are drawn. After some experimentation, I think that the document thumbnails as well as the Impress template icons are both rendered using following steps: 1. An offscreen image is created 2. The offscreen image is cleared in white (this is what turns yellow) 3. The thumbnail image is drawn with an alpha mask on top of the offscreen image 4. The offscreen image is drawn to the window What is interesting to me is that I if I try to skip step 2 by disabling drawing filled rectangles in SkiaSalGraphicsImpl::privateDrawAlphaRect() and drawing filled polygons in SkiaSalGraphicsImpl::performDrawPolyPolygon(), the offscreen image is still filled with white. So, my current theory is that erasing the background of an offscreen image is where the problem might be. My logic is that LibreOffice colors set alpha values to 1 - Skia's alpha value. What this means is that LibreOffice white color in ARGB format is #00ff. Copy this bit for bit directly to a Skia white color in BGRA format results in yellow. I post more when I find the code that clears offscreen images. -- You are receiving this mail because: You are the assignee for the bug.

My current theory is that SkiaSalGraphicsImpl::mergeCacheBitmaps() is doing something unexpected on some machines. I have posted the following patch that prints out some debugging data that I am hoping will narrow down the what is causing this bug: https://gerrit.libreoffice.org/c/core/+/144814/2 If anyone who is experiencing this bug and has a LibreOffice build is willing test out the above patch, can you apply the patch, make, and then do the following steps and post all of the "warn:vcl.skia.debug" messages that appear in the Terminal?: export SAL_DISABLE_SKIA_BITMAP_MERGE=1 ./instdir/LibreOfficeDev.app/Contents/MacOS/soffice 2>&1 | grep vcl.skia.debug When LibreOffice launches, open the About dialog, then quit. In addition to the Terminal messages, can you tell me if the large images in the About dialog are still colorshifted like in attachment 176623? -- You are receiving this mail because: You are the assignee for the bug.

From the screen snapshots attached to this bug, it appears that somewhere RGBA pixels in Skia bitmaps are getting incorrecting converted to RGB or ARGB pixels.

Nice > There are lost of comments here, so I’m not sure what I can help with > debugging this. The issue is bit specific sub-set of Mac; until now only non-dev users could reproduce it. The Skia expert - Luboš Luňák - couldn't, which made debugging really hard. Easiest route maybe pinging Luboš at the libreoffice-dev IRC channel for some guidance. He might lost interest on the Mac part, though..

Note, my personal opinion: Skia should be enabled by default on Mac. I'm not getting why it should be disabled for 7.4 again. The major random crashing bug with Raster has been solved. There obviously bugs, but well that's always the case in the beginning. The user group is pretty small if not being set default. Using the the Skia platform has quite some advantages (especially speed) Yes, this bug needs attention never the less, but it's surely not a general Intel Mac issue. I have 2 Intel MacBook's at my disposal, but I can't reproduce the issue described here.. It's a specific Intel chipset and/or specific driver or firmware causing this, I guess :-( And well there is a easy work around, disable Skia manually. So this bug should be a blocker for setting Skia Default, IMHO -- You are receiving this mail because: You are the assignee for the bug.

If somebody here would have the time and can do at least basic coding, vcl/skia/README has a section on debugging that describes how to find out which drawing calls are responsible, that could be useful here. -- You are receiving this mail because: You are the assignee for the bug.

Ah, non-practical -- I'm so not up to speed with the version numbering of macOS (not), and even not to aware of the last major version. Anyhow, I'm currently running 12.01 Monterey. So the version detection at LibreOffice being broken (again) -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=145988 --- Comment #8 from steve --- About will read "10.16" for any Big Sur version so if you are on macOS Big Sur 11.6 it would be 10.16 in LO about. I manually change that info to the correct value "11.6.1" because LO is unable to do so. This awkward situation is explained here: https://eclecticlight.co/2020/07/21/big-sur-is-both-10-16-and-11-0-its-official/ So you are running 11.6? You can see that info by clicking on the Apple icon top left > About this mac. This would be an interesting finding if the issue was introduced with the 11.6.1 update while 11.6 works as expected. -- You are receiving this mail because: You are the assignee for the bug.
