Screenshare stuttering

[haroldojunios]

When I screenshare the mouse cursor starts to stutter on my side, and all the stream stutters for the viewer, as if old frames are being shown in the middle of the new ones. This happens on any browser and OBS.

I have had the exact same problem with Nvidia 560 drivers since I started using Hyprland. I have tested open-dkms and dkms drivers, as well as the xdph git package with a lot of different environment variables and settings.

This is one of the few things that really bothers me about Hyprland, I would be happy if there is a solution for it

[id3v1669]

had same problem, enabling render:explicit_sync = 1 seems to fix the issue. That brings it's own problems, but at least screensharing works for me.

[Elibrio]

Hmm I thought I had already tested this, but it actually seems to fix the problem for the most part. It's still visible sometimes, but hopefully that will change in the future with driver optimizations. Thanks a lot!

[haroldojunios]

It's good enough for me, thanks @id3v1669.
