Public bug reported:
I'm Using Ubuntu 26.04, I have nouveau-drivers and VLC media player
3.0.23 Vetinari (revision 3.0.23-2-0-g79128878dd)
I start vlc in any way, even in debugger, open any video and then skip
it rapidly to the end. Video hangs. I can close the vlc window, but the
process stays on the background and prevents me from starting new Vlc. I
have to use kill -9 to get rid the process.
This happens every time when I try it. It is a bit annoying in daily
use, but you can work-around it if you know how to use kill -9.
I will attach stacktraces I gathered after the hang. Here is also normal output
from vlc from different run
in case it provides more info.
$ vlc
