Bug description:
Crash happened a short time after starting a screen cast / remote
desktop session using the Freedesktop portal API in a Wayland session
with mouse and keyboard input. Screen cast continues to run (i.e.,
PipeWire stream), but input stops.
Can be reproduced by using the experimental Wayland support of
TeamViewer
