I’ve been testing a video editing setup on CentOS Stream and keep running into a really frustrating issue where hardware acceleration randomly locks up during exports. The video editor capcut itself works normally at first, timeline playback is smooth, GPU usage looks fine, but during longer renders the entire UI suddenly freezes while GPU utilization spikes to 100%. Sometimes the export hangs permanently, other times the app crashes silently without producing a full output file.
What’s strange is:
- CPU-only export works (very slow though)
- The issue appears mostly with H.264/H.265 exports
- Happens more frequently after recent Mesa/NVIDIA driver updates
- Journal logs don’t show anything clearly useful besides occasional GPU reset messages
I’m trying to figure out whether this is a driver regression, VAAPI issue, or something related to hardware encoding support on CentOS Stream itself.
Has anyone else seen similar behavior with GPU-accelerated media apps recently?
