ASUS TUF Gaming VG279Q1A not working properly after getting too cold

Level 7

I accidentally left my window open over-night allowing temps in my room to drop below freezing.

Now, whenever temps in my room drop below 70 degrees F, a bar of pixels (about 1" thick and 2" from the top of my monitor) start to glitch out, and all the rest of the screen below the bar will lag and freeze. The top 2" of my monitor works perfectly 100% of the time.

Now this is the weird part: whenever I bring a non-full screen window to just above the glitchy bar of pixels, the monitor works again. If I have any full screen window, it starts glitching again. I've also noticed when I play games the monitor is worse when I quickly look around, especially in darker games with more black pixels (racist monitor?) I think it has something to do with pixels quickly being turned on and off in the bottom section of my monitor, but that still wouldn't explain why having a non-full screen window would suddenly fix the problem (I've tried moving it around too: a white window extending to the bottom of the screen moving over a black, full screen window, works just fine, but if the window is then minimized and I interact with the full screen black window, the effect comes back.)

Does anyone know why this could be happening and have a solution, or should I just toss the monitor?
