flickering

As soon as I open the OBS program on my mac the program flickers lines before I can even touch anything. Most forums I've looked at are to do with flickering happening when you start streaming but mine is as soon as I open the program. I have the latest update

Ring of Elysium: My game is presenting this problem: everywhere everything becomes pink, pink lines, the characters and the scenery stay with these pink lines. (I'll attach a print of the game) How do I solve it?

Hey recently I had this problem where my monitors start flickering when my game is full screen and obs is on my second monitor. It flickers fast but when OBS preview is off it flickers slower. I don't know this problem and I was going to talk in Community chat but my stupid friend IP banned me...
