Unity UI seems to be glitching out?

In editor mode, simply selecting different element in the UI in the hierarchy is causing the canvas UI to glitch out. If I play the game, the UI constantly flickers. There’s no script doing anything to the UI in game and there certainly isn’t one doing anything to it in the editor. What is going on here? I’m using Unity 2022.3.20f1. Is the canvas just broken in that version? If so, was it fixed later?

Here is a video of it glitching out

Have you tried a newer release of 2022.3? I remember a similar bug from a while ago that should be fixed in newer versions already but can’t seem to find a link right now. If it’s still happening I suggest you submit a bug from inside the Unity Editor through Help > Report a Bug.
