3 years ago Hi @iinuwa , could you please go to about:support, click "copy text to clipboard", and attach that information to this bug?
Would you be able to run mozregression to determine what change introduced the bug. You need to have USB debugging enabled on your device, and plug it in to your computer. Then you can install the mozregression GUI from that link, or if you're running Linux or Macos you can install the command line version with pip install mozregression. Then you can run mozregression --app gve --good 88 on the command line, or launch the GUI and make sure you select "geckoview example" as the application. This will then install a series of versions and you can answer whether it is good or bad, and eventually it will find the change which caused the issue. If you need any help with that please feel free to ask! Thanks

3 years ago I assume I should be using --app gve (GeckoView Engine?)
This is the information from the last "bad" build from mozregression.

I'll try to post the text from my phone later; it's exhibiting the same bug, so I can't see the whole screen. :laughing:

URL Thanks @iinuwa that's really helpful.
Could you also try going to about:config, setting gfx.webrender.allow-partial-present-buffer-age to false, restart, and see if that helps. If not, then try setting gfx.webrender.max-partial-present-rects to 0 (zero), restart, and see if that helps?
@kbrosnan It seems like this isn't actually a duplicate of #19348 (even though it looks similar), due to this being on Adreno rather than Mali-T.

commented
3 years ago @jamienicol: None of those combinations (allow-partial: false, max-partial: 1; allow-partial: false, max-partial: 0; allow-partial: true, max-partial: 0) made a difference.
jamienicol
commented
3 years ago Thanks. I think that's expected, because partial present should be disabled by default on your device, because we already had seen it reported as being buggy. So this issue isn't related to partial present.
Could you try running mozregression again, this time with --pref 'gfx.webrender.all:true' (as well as --app gve as you said). Then try running an old version and see if you can see this bug. (I expect you will see lots of unrelated bugs on older versions, but just try to say good or bad depending on if you can see the same bug as in your original screenshots)

3 years ago Took a while! I didn't immediately notice any other weird unrelated bugs, so that's interesting
With WebRender force-enabled, I got this:

3 years ago Thanks @iinuwa, that's interesting. I think I may need to get my hands on one of these devices to investigate this further.
In the meantime, if you weren't aware, you can set gfx.webrender.force-disabled to true in about:config to work around the bug.

3 years ago Sounds good. Should this be reopened then?
Let me know if you want anymore testing done.
In the meantime, if you weren't aware, you can set gfx.webrender.force-disabled to true in about:config to work around the bug.
Ah, that works. Thanks!
Steps to reproduce
Open any website.
Expected behavior
Full webpage is drawn correctly.
Actual behavior
Large portions of the screen (mostly large rectangle at the top and bottom of the viewport) are just black rectangles. During scroll, the rectangles flicker in color, but the content that should be rendered on those rectangles is never drawn. (That is, I can see some content in between the black rectangles, and if I scroll past a black rectangle, I can see more content followed by another black rectangle. But I can never scroll in such a way that I can see the blacked-out content.)
Tapping the screen seems to still work; I can long press and get links and contextual information. So it seems that it's just drawing the screen is having an issue.
This is similar to #19348 and #19342, but the rectangles are much larger on my screen, always flicker and appear on every website I visit. Also, those two issues reference Mali GPUs, but this is a Qualcomm GPU.
This began happening on my device some time last week.
