5 years ago This type of panic might be more likely to occur when using OpenGL 3.1 (instead of XRender) as the compositor rendering backend.
Maybe ignore that thought.
This panic occurred with XRender. IIRC after I copied Control-C from Geany, aiming to paste to Waterfox (can't recall whether I got as far as the keyboard shortcut for the paste):

This type of panic might be more likely to occur when using OpenGL 3.1 (instead of XRender) as the compositor rendering backend.
Is it a duplicate of #149 or does use of
drm-devel-kmodmake this issue distinctive?…
