It seems my comment didn’t send but I plugged the HDMI cable to another port on the monitor and it got rid of the big glitches, however a small portion of them still remains. My GPU seems to be connected correctly as well and these glitches are not present in Windows. I’m updating the OS as we speak I’ll see if anything changes

one more thing, for some reason after I installed the GPU it does this glitch thing yes. I tried rebooting

a question i have: I use pop!_OS and I installed it using the Nvidia ISO, will there be a problem if I switch to an AMD GPU?
