I'm not sure it's Falkon or QtWebEngine issue, but with newer Mesa 21.3.x webengine view has some blinking, no issue on any other components. I just update, staying to 21.2 till now.
Falkon and Mesa 21.3
The issue https://gitlab.freedesktop.org/mesa/mesa/-/issues/5731
The fix https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14505
@demm can we have new mesa build?
Mesa 21.3.4 is in the build repo since 2 days, tested if it includes the above patch (from 3 days ago? (or, which mesa are you reporting).
- Edited
The patch is not officially merged yet. It could be part of 21.3.x where x >= 5.
Patched Mesa is now up in the build repo, please report if that fixes your issues (I don't see it, so can't check).
I had hoped the patch would be merged before applying, but the MR keeps showing as blocked
, no indication why, looks like it won't be part of Mesa 21.3.5. So this patched version won't move until it is shown it is an improvement.
I applied by myself, since using only Falkon, it was unusable. No issues since then, thanks for the fix.
