transparent windows

SUMMARY
It started to happen somewhere in Nov 2021. When i login to Plasma(Wayland) session and i start some app, like konsole then it starts but its window content are transparent. Almost all KDE applications behaves like that. i found nothing in journalctl, even with mesa or qt in debug mode.
What is important if i login into Weston session from sddm, then everything works like expected - no transparent window content.


STEPS TO REPRODUCE
1. Login to PlasmaWayland
2. start konsole - see transparent window content
3. start falkon - see transparent window content
4. start systemsettings  - see window content behaves like expected

OBSERVED RESULT
Transparent windows content under Plasma Wayland

EXPECTED RESULT
See real windows content

Can you post the output of `qdbus org.kde.KWin /KWin supportInformation`? Windows are rendered as expected if I force GLES
Comment 3 Tomasz Paweł Gajc 2022-06-30 20:19:19 UTC
Hi,

Looks like there were some problems with mesa, because after couple of upgrades things started to work on aarch64. IMHO this can be closed.

[tpg@omv-rockpro64 ~/OpenMandriva/rpmlint]$ LC_ALL=C qdbus org.kde.KWin /KWin supportInformation
