Hi, This problem doesn't seem to be in the celluloid code, but it seems to me to be a GTK 4 rendering problem that is occurring on some hardwares that started in GTK 4.16 and I saw this in the backtrace when reporting in the first lines vl_compositor_gfx_render. This occurs on my machine if I don't set GSK_RENDERER=gl in /etc/environment and that you can configure if your hardware is Nvidia or AMD (see links[1][2][3][4]).
And it would be interesting if you could mention what your hardware would be with inxi, if you prefer, or any other way that also helps us to check if it is a problem that occurs specifically in some hardware such as this. There is a patch in Debian that changes the default renderer back to ngl[6], but in your case, if it is not, this may be another problem and it would be interesting to do some tests. But running on my machine, I have no problems in Debian testing/sid and in Mint (Ubuntu 24.04) with this package using version 0.26-1.
