--- Comment #9 from Tom <t...@posteo.de> ---
Hello, thanks for the help everyone!
1. I didn't manage to do the backtrace via ssh after a crash (need another pc),
and currently I am not able to reproduce the crash properly. I think this might
be because I deactivated some desktop effects and maliit-keyboard, if I manage
to figure out what is causing this I will update.
2. The visual glitches (see screenshot) are present on both X11 and Wayland.
During the glitches there is actually no gdb stack. Are there other debugging
tools to identify the cause of the glitches?
3. I finally managed to get a stack during a glitch which might be the same
issue or a separate one. It appeared the moment I clicked on "Open" in the
filepicker while trying to share a file using LocalSend (via Flatpak
https://flathub.org/apps/org.localsend.localsend_app). Not sure if it's related
to the file picker, I couldn't reproduce just now.
Here's the stack via GDB:
