SUMMARY *** Using AMD iGPU of my AM5 on the Host, as soon as I start my Computer with Kernel 6.2.1 / 6.2.2 the screen starts flickering. I could narrow it down thanks to the help in the arch forums https://bbs.archlinux.org/viewtopic.php?pid=2087933#p2087933 to the compositor, currently writing this on 6.2 and x11 with suspended the compositor (SHIFT+alt+F12) to remove the flickering. *** STEPS TO REPRODUCE 1. Arch installation with current 6.1 LTS and 6.2 2. Boot 6.2 and Login to X11 User Session -> Flickering 3. Reboot to 6.1 LTS and Login to X11 User Session -> no Flickering 4. Boot 6.2 and Login to X11 User Session -> Flickering, Disable compositor (SHIFT+alt+F12) -> no Flickering OBSERVED RESULT Links to two videos: https://imgur.com/E712RcP https://imgur.com/TKhXO5l EXPECTED RESULT No flickering with enabled compositor on X11 SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.2.2-arch1-1 (64-bit) / LTS 6.1.14-1-arch1 (64-bit) Graphics Platform: X11 ADDITIONAL INFORMATION Processors: 32 × AMD Ryzen 9 7950X 16-Core Processor Memory: 62.0 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: ASUS
If there is anything that I can provide (logs etc) please let me know which one you'll need etc.
Okay seems that one is fixed - not sure why/how/which package it was but latest updates/packages on 6.2 solved the flickering in picom and kwin.
Fixed
