Created attachment 171662 [details] Backtrace output from error dialog on login. SUMMARY When my laptop is plugged into a monitor and then turns off the monitor, there's a chance for the lock screen to have its effects bugged. The lock screen still works, it's just the effects applied that gets buggy. STEPS TO REPRODUCE 1. Plug laptop to separate monitor and keep the laptop screen also open. 2. Let the monitors sleep by the lock screen. 3. Awaken the device. OBSERVED RESULT When the monitors wakes up and lock screen appears: - The profile picture is missing a white frame and is a rectangle instead of a circle. - The shadow and blur effects have disappeared. The lock screen does work as usual, and you can unlock and continue to use the desktop as normal. EXPECTED RESULT The lock screen should be able to keep its effects. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.1.2 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION I wasn't sure what product to report his as a bug in, but when error dialog shows up on login. It seems like kscreenlocker, but the backtrace always says there's a segfault on plasmashell.
Thanks for the bug report. Are you still seeing this in Plasma 6.3.2? If you are, we need some additional information. Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: #8 0x0000715833a6f112 in ?? () from /usr/lib/libQt6Gui.so.6 #9 0x0000715834818647 in ?? () from /usr/lib/libQt6Quick.so.6 #11 0x00007158330c9747 in ?? () from /usr/lib/libQt6Core.so.6 Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

I haven't been able to replicate this bug as of late, as I have switched primary computers and a different distro.
