Created attachment 153236 [details] gdb_session.log SUMMARY plasma-kscreen-osd.service crashes when activating the monitor configuration key on a laptop. All functionality seems to still work, which seems to be because it crashes in the destructor. This is fully reproducible. A log of the coredumpctl session is attached. STEPS TO REPRODUCE 1. On a Lenovo Thinkpad P15 Gen1, press Fn+F7. This brings up a OSD display to change the external display config (mirror, extend left, ...). This appears to work correctly. 2. Notice how the systemd user service plasma-kscreen-osd.service is now crashed. OBSERVED RESULT A crashed systemd unit, plus a core dump in /var/lib/systemd/coredump/. EXPECTED RESULT No crash? I mean, that is what I usually expect at least! SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 5.26.2 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION The laptop has nvidia graphics and is running in nvidia mode (not intel or hybrid). I don't know if this makes a difference. I can't test that however, as the external monitors are connected directly to the nvidia GPU and thus won't work in intel mode. Additionally, hybrid mode is very unstable and crashy preventing testing that entirely.
If something crashed, we need a backtrace of it so we can figure out what's going on. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports. Can you please attach one? Thanks!

I did, sorry. Thanks for the detailed debugging data.

(In reply to whatifgodwasoneofus from comment #7) Could it be smth related to Qt5?
(In reply to whatifgodwasoneofus from comment #8) NEW INFO: The crash only happens if I attach the cable to a port that is directly controlled by (soldered to?) the discrete GPU. If I attach the cable to another port somehow managed by the Intel GPU, kscreen behaves properly. I am using the _prime_ drivers.
