I recently picked up a used RX 6600xt, and ever since the screen will occasionally freeze for 1-2 seconds before returning to normal. As far as I can tell, input and sound work as normal during these. There’s no real pattern either.

I’m on Mint 21.3 Cinnamon, on the 6.5 kernel (there was a sleep related issue for me in the default kernel version). Since getting the GPU, I’ve replaced the CPU and motherboard.

Any guesses as to what this might be, or where to look? I tried checking mint’s logs app and there didn’t seem to be anything associated with it.

    I remember there being a bug with AMD GPUs and monitors with freesync a few kernel versions ago. It’s exactly like you said, random brief freezes.

    Try updating to a newer kernel or disable freesync in your monitor settings (if appplicable).

      Looks like freesync was the issue - I turned off the setting in my monitor and the issue hasn’t reoccurred. Thanks for figuring that out!
