Video recording (obs source freezed after screen dimming)
I have the exact same issue. Not all Qt apps are affected though, VLC for example is still responsive after the monitor wakes up. It looks like only KDE apps are affected. Can you get the backtrace of a crashing app? Also could you please capture the output of such an app while it runs with the WAYLAND_DEBUG=1 environment variable set? it may require ssh'ing from another computer Created attachment 146484 [details]
Dolphin output with WAYLAND_DEBUG=1
Here is the output of Dolphin 21.12.2 with the WAYLAND_DEBUG=1 environment variable set, after turning off then on a DisplayPort monitor.
The output is very large, I suppose it starts to be relevant at line 1018: "qt.qpa.wayland: Creating a fake screen in order for Qt not to crash"

Dolphin unresponsive
KDE apps such as Dolphin, Yakuake (when it is visible) or System Settings, etc. no longer seem to crash, but they become unresponsive for a while after the screen wakes up (the window is greyed out, as in the screenshot attached).
After a minute or so the applications can be used normally again.
I am having the same issue. Freeze of kde apps, Konsole and Kontact mainly as they are often visible but no crash for me. GPU: AMD RX 5700 XT (with Mesa 21.3.6) Plasma version: 5.23.5/5.24.0/5.24.1 Frameworks version: 5.90.0/5.90/5.91 Distribution: Fedora 35 On another laptop I don't experience that. It has an Intel gpu, maybe it is linked. Where I have the issue, I also have steam installed with all the i686 dependencies. Maybe linked too... Tell me if I can help with debugging It looks like it's fixed on my end now! It may be related to the Plasma 5.24.3 or Qt 5.15.3 updates. Oh great! (In reply to Yannick from comment #7) > It looks like it's fixed on my end now! > It may be related to the Plasma 5.24.3 or Qt 5.15.3 updates. It must be the QT 5.15.3 patch that fixes the issue. In fedora, the patch hasn't landed and with plasma 5.24.3 and qt 5.15.2, I still have the issue. Waiting for the qt patch to land :) *** Bug 450679 has been marked as a duplicate of this bug. *** Looks like Debian unstable / testing is *finally* getting newer Qt, so this nasty bug will hopefully be fixed: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1007170 Debian testing finally after a huge wait got a newer Qt (5.15.4) and this bug is gone! |
