Dear Maintainer, The latest update from kwin 4:5.24.5-1+b1 to 4:5.25.4-2 has made KDE very unreliable for me: every other day, the entire session just basically freezes up; I can still move the cursor, but that's about it. Just before that happens, I usually get a black rectangle in the bottom right corner of the screen, where the Plasma notifications usually appear. At that point I can still interact with the foreground application, but if I do alt-tab, then the session is doomed and I need to Ctrl-Alt-Backspace, losing all unsaved data. Also see https://bugs.kde.org/show_bug.cgi?id=457847. Kind regards, Ralf
I got this bug too. But only in my notebook. I have another computer and
kwin-x11 does not freeze. Maybe because my computer uses a nvidia GPU and
my notebook uses an onboard Intel Graphics.
One workaround is open konsole (Ctrl-Alt-T) and restart plasma with this
command:
killall -9 plasmashell && kstart5 plasmashell
When kwin crashes I got these syslog messages:

Maybe it is related with opengl but, even disable composing, I got kwin
random freezing hours later.
Hi, That bug was determined to be caused by https://gitlab.freedesktop.org/mesa/mesa/-/issues/7674. I *think* (but haven't confirmed yet as that doesn't seem trivial to do) that that bug should be fixed in mesa 22.3 which is in bookworm since 2023-01-02 (and in unstable since 2022-12-01). So if this bug reoccurs for somebody, it would be good to update the bug report. I had the same issue as in this report and decided today to investigate. However, my system updated mesa yesterday, so if my searching is true, the bug should be gone for me. I think this bug (and maybe similar bugs) should be reassigned to mesa, raised in severity and closed... (or just the latter). Paul
I think I have this bug. If true, it's still present. I'm on mesa 22.3.3-1. I upgraded this system on the 7th and started having the issue. My entire desktop freezes. Seconds on the clock stops. My mouse cursor still moves but I can't interact with anything. My music player keeps playing. I can get to a console with ctrl+alt+f5 and it shows very low CPU activity. Nothing in syslog or xsession-errors. I have to restart sddm or something similar. I think the trigger is when I do an alt+tab switcher activity. I have a near-identically configured/versioned laptop and don't see the issue there. It's using an internal Intel GPU while my freezing desktop has an AMD RX 570.
I don't think that mesa upgrade changed anything, I still get the
hang regularly. Restarting plasmashell sorts it out.
