Created attachment 126154 [details] New crash information added by DrKonqi org_kde_powerdevil (2.0.0) using Qt 5.13.2 - What I was doing when the application crashed: in wayland. Unplugged the power, hdmi and usb keyboard at same time. KDED and systemsetings (looking at displays) also died. -- Backtrace (Reduced): #6 0x00007fb0cca38564 in KWayland::Client::OutputDevice::enabled (this=0x563fb836cfb0) at ./src/client/outputdevice.cpp:535 #7 0x00007fb0cc3bd566 in KScreen::WaylandOutput::updateKScreenOutput (this=this@entry=0x563fb8359dc0, output=...) at ./backends/kwayland/waylandoutput.cpp:102 #8 0x00007fb0cc3be7fc in KScreen::WaylandOutput::toKScreenOutput (this=0x563fb8359dc0) at ./backends/kwayland/waylandoutput.cpp:94 #9 0x00007fb0cc3b5e0e in KScreen::WaylandConfig::currentConfig (this=0x563fb82e4db0) at ./backends/kwayland/waylandconfig.cpp:294 #10 0x00007fb0cc3b3cb3 in KScreen::WaylandBackend::<lambda()>::operator() (__closure=<optimized out>) at ./backends/kwayland/waylandbackend.cpp:45
Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!

Thank you! I cannot as I unfortunately don't have the mentioned system (TP T460s using Intel i915 graphics) anymore. With the T14s Gen1 (AMD) I never experienced this issue.
OK, thanks!
