[arch-general] Problems with Gnome or Xorg (?)

Hello, I've been experiencing some visual glitches in Gnome or Xorg (I guess?). I can't really describe exactly what is happening but here are some examples of weird behaviors: 1) Sometimes, when I change tabs in my web browser (Google Chrome), a region from the previous web page gets stuck and I need to change tabs a number of times to return to normal behavior. 2) In Chrome, sometimes, when I exit full screen, several visual glitches happen and I must also change tabs. 3) In the game Klotski, when I repeatedly click on the pieces, small details change. Do you have any suggestions that might help me fix this?
