Well. Tried latest updates … [Stable Update] 2022-12-20 - Kernels, XFCE 4.18, KDE Frameworks, Kde Gear, Mesa, Plasma-Mobile, Thunderbird, Firefox. Update itself went without problems.
But situation around mesa higher than 22.1.7 causing trouble for Firefox startup persist.
- So we are lucky and still have packages from 22.1.7 version of
mesaand we can downgrade to this version of?-mesa-?,?-vulkan-?packages. (or other version that worked for you). - Or endure, go along with upgrades and manually kill highest PID of Firefox to let it continue.
As I read this is unrelated to removal of video codecs from open source AMD graphic mesa driver (22.3+). Since my trouble started at start of november already. And that is moving from mesa version 22.1.7.
