small bump about it.
@mods, same problem but i got it with arch, if you want to move my post to a new or so, pls do. i just thought to also add my problem here onto the existent problem
got the same error messages all over my journal with lutris and trackmania2020.
Its so bad it completely floods my journal and ingame the screen is literally frozen and unplayable.
Setting or not setting DRI_PRIME=1 does not change anything.
UPDATE/FIX
Add
KWIN_DRM_NO_DIRECT_SCANOUT=1to/etc/environmentand reboot.
