Hello!

I bought a PG79Q monitor and this is the third one so far with an annoying screen glitch. Randomly, when switching between applications (using alt-tab), a strip of pixel content from the right side of the screen is replaced by an equal-sized strip of content on the middle of the screen. It's not static, so if I say put my cursor in the middle of the screen (in the "strip"), it would show up on the right side of the screen.
Since it is the third monitor with this problem I believe that it's not the monitor that's causing it, but I'm not certain. Has anybody had this problem before? Any solution?
