--- Comment #7 from Ike <fancyname+kdebugtrack...@use.startmail.com> --- Wow, sorry guys for ignoring this for such a long time, shame on me... I was actually using my system without the compositor since this issue. I've just retested everything. The situation has changed for good but there are still some problems: - When using OpenGL 2.0 or 3.1 and setting vsync to "Re-use screen content" there is no flickering, but most windows don't refresh anymore at all. The system is totally unusable in this setting. - In all other settings, i.e. other vsync options unter OpenGL and all vsync options under XRender (incl. Re-use screen content) everythings fine, only observed flickering in the taskbar when hovering over it (as described in my original post) How should we proceed with this? I can still try to downgrade to the kwin version before my initial post if you tell me how I can do this without breaking my system 😅 Current SOFTWARE/OS VERSIONS kwin-x11 - 4:5.20.5-1 Linux: Debian testing (Bullseye), kernel 5.10.0-11-amd64 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 -- You are receiving this mail because: You are watching all bug changes.
