Created attachment 148710 [details] GDB trace my Plasma session was locked when strangely the laptop went into sleep mode. When I have awaken it, and I unlocked the screen, I saw all opened applications have disappeared. I collected the GDB trace of kwin crash, see attachment. A short resume of it is: Core was generated by `/usr/bin/kwin_wayland --wayland-fd 5 --socket wayland-0 --xwayland-fd 6 --xwayl'.

Thank you for helping us make KDE software even better for everyone!
(In reply to Vlad Zahorodnii from comment #2) > it would be nice to have a reproducible scenario otherwise the bug report is inactionable. I don't have a way to reproduce it
Okay, it sucks but there are debug symbols so it should provide at least some context. In general, it looks like a crash in Mesa. Please report this issue to Mesa developers. Also, please check whether the issue is still present in latest plasma + mesa.
