So this happened just 10 minutes ago. It's never happened before and I was just browsing online when it happened. Suddenly the screen started flashing/pixelating in the upper left hand corner. I tried to screenshot it in hopes it was just Firefox, but it didn't show up in the screenshot
I also noticed it did it on my desktop too, not just on Firefox. Would this be a graphics card thing? Is it bad news?
It happens randomly in bursts, it just flashes on and off really quickly.
I can kind of "erase" it by highlighting my desktop under it sometimes.
Help!
Edit: Oh god it went over even further this time
