Comment 2 Morgan Leijström 2023-07-06 16:22:46 CEST

Have you verified if VLC works with a an install of only another DE on same machine?

What is the output of 
$ inxi -G

yes, it does work fine on all other single DE installs from that CI .iso
(Plasma, Gnome, Cinn, Mate, Xfce, LXDE.)

Now on LxQt (multi-desktops).
I tried this first on Cinnamon, and did not notice anything untoward. But the effect is so subtle, I may have to go back & check.
On a short mp4 video, nothing noticeable.
On a longer Indian knees-up mp4 video, I noticed a single slight jerk at about 5s only, after starting the video from scratch.
Leaving it in place, and re-winding to the start, I did not see it again.
I think I could see the same behaviour with a webm video.
FWIW...

Is this issue still present in current Cauldron? It is almost a year later and most of Cauldron has changed.
