STEPS TO REPRODUCE
1. Install KDE 6.1.1 (or older version) on hardware with video card i915
2. Check the logs
OBSERVED RESULT
Issues with graphics rendering.
Also separate issue with login screen SDDM without text. I have created
separate bug report: https://github.com/sddm/sddm/issues/1958
EXPECTED RESULT
No rendering issues
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo
(available in About System)
KDE Plasma Version: 6.1.1
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1
