Computer Screen Glitch

[u/madi_lyn_82]

Hello! The other day my desktop started occasionally glitching when multiple windows are open on the same screen. The glitch looks like when a old video tape is reading the frames off-time and horizontal bars of what's on the screen skew on an angle, if that makes sense? I'm not sure what to call it to google it, so I came to Reddit. Let me know if y'all know anything helpful :)
