The lower part of my screen is updated one frame earlier than the upper part. I was able to isolate the error to the HDMI output of my laptop. The screen or cable is not broken, as I don't get these errors with other connected devices. I am assuming it is some hardware defect. Does anyone know what it could be and how I could fix it? Here are a few pictures that show the problem: pixelfed
Solved: Ok, it seems to have been a software problem. That had to do with the sync. I have installed ubuntu on the laptop for now and everything works again. Some update seems to have shot something. I am now using a LTS version.
Edit: I want to add that this problem occurred from one day to the next. I'm using Jellyfin as playback, but this effect even occurs when moving windows over the screen
is refresh rate auto switching enabled?
This is likely a Jellyfin issue as auto switching may not work on multimonitor systems and especially when moving the player between windows.
not that I am aware of. How could I find this out?
I'm not familiar with Jellyfins current UI as I havent used it since the very first beta releases, but it will be in the settings somewhere.
