SUMMARY
Hello, in Ubuntu 25.04 Beta (Plasma 6.3.3) the Wayland session works fine, but on X11 all the Plasma shell seems to crash after the screen goes in standby and the session is locked.
The desktop is completely black and the panels are not visible anymore. The system still work because I can press the Windows/Super key and the kickoff menu appears and it work. Also dolphin works fine, but the desktop remains black as the panel at the bottom of the scree

STEPS TO REPRODUCE
- Enable the automatic power off "Turn of screen after X minutes"
- Let the screen go in standby
- Press any key or move the mouse to make the screen turn on again.

OBSERVED RESULT
The desktop is totally black and the panel is not shown

EXPECTED RESULT
Should work as usual

Adding journalctl, if it can be useful

If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?

Thanks!

Hello, Ubuntu doesn't have coredumpctl because it uses apport and, in this case, apports doesn't report any bug.
I tried to create a backtrace using "gdb --args plasmashell --replace" but nothing seems to crash. The problem occurred, but the crash has not been reported by gdb.
