Abort trap (core dumped)
$Again, this is FreeBSD 14.0-RELEASE-p4 amd64 with FreeBSD clang 16 and Qt 6. The entire thing is running in a pure Wayland environment.
Reproduce
The issue seems to be quickly reproducible by producing output to the terminal and moving the mouse at the same time.
I did this by running: while :; do ls -lapho; done and then moving the mouse. Contour then crashes within milliseconds.
