Finder starts to glitch more often

Finder recently started to have these glitches:

1. left side of menu bar (at the top of the screen) fails to work. while I am on other apps and attempt to click it, it will immediately change to Finder's menu. However, none of the menu options will be clickable.
2. desktop icons will be shown over other apps' open windows. menu bar shows that I am on Finder.

Not sure what exactly triggers these glitches. Force quitting/restarting Finder or restarting my mac does help, but the glitches will come up again later on, so these are just temporary fixes. I am on macOS Monterey version 12.1.
