Unable to play video in laptop with NVIDIA T1200

When trying to play any video (with firefox or chrome) in a laptop with openSUSE Tumbleweed (kernel 6.4.12 Driver version: 535.86.05-10.1), the audio plays fine but the video gets frozen in some frames and gets desynchronized (is frozen some seconds, then some jumps, then completely stalled…).

WebRTC conferences, on the contrary work as expected.

How could I debug this issue? Any hint of where could I start?

A couple updates ago, video playing was working fine (but I cannot switch back to one of the working snapshots…)
