Hey Folks, since some days I’ve been migrating my “gaming rig” from Win 10 to Ubuntu. By now everything works like a charm and thanks to Proton I’m even able to play basically all the games I played on Windows now on Ubuntu as well - awesome!

But I’ve noticed something weird. One of my screens is a 4K LG TV (nothing special, really old one but supports 60Hz). I’m using this screen usually to stream some videos or movies to the living room or to play some games on the big screen. On Win 10 there is no issue here. On Ubuntu 22.04 I have a weird micro stutter every 3-4 seconds. The TV ist connected via HDMI. My other Screen which uses HDMI as well is working fine. Graphics Card is a NVIDIA GeForce 1070 with Nvidia-525 drivers (can’t use Nvidia 535 drivers because somehow Steam does not work with them by now). I’ve already tried playing around in NVIDIA System Settings (turning on Full Composition Pipeline and such Things) but nothing really helped. Do you Guys have another idea? I don’t think it is Hardware related because when I boot into Win 10 the screen works like a charm.
