I upgraded my dual monitors from a pair of 60hz to 144hz. It's been 8 years since I've gotten new screens, so I thought it would be a good idea to install the new monitor and graphics drivers. Since upgrading, I've gotten these weird graphics glitches/flickers.
I'm not sure what triggers it. They only appear when I'm using both monitors. If I turn 1 off, the glitches stop. It's not limited to intensive use. These glitches can happen even when I'm just browsing the internet.
I'm not sure which version I was on before. Currently I have 20.4.2 installed. I've tried rolling back as far as 19.10.2.
