--- Comment #1 from TraceyC <kde...@tlcnet.info> ---
I tested with Xournal++ in KDE Neon User running Plasma 6.3.4, but I'm not able
to reproduce the hang. I'd like to ask a few questions to help narrow down the
cause.
Does this happen on your system with X11 apps other than SDL3?
If you open the Crashed Process Viewer, do you see anything with a timestamp
from around the time your system hung?
If there aren't crashes around that time, please try getting logs of the hang
by running these two commands:
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
sudo gdb -pid $(pidof kwin_wayland) -batch -ex "set logging file
kwin_wayland.gdb" -ex "set logging enabled on" -ex "continue" -ex "thread apply
all backtrace" -ex "quit"
After you reboot, you should have a log file "kwin_wayland.gdb" in your home
directory
Then start SDL3 and cause the bug to happen.
