Random artefacting when a game is in background

https://streamable.com/r9c6l6

1. i get this artifacting on all programs for a second or two sometimes when i have a game open in the background. it obly recently started happening. what could be thr issue? i already downgraded gpu drivers
2. similar artifacting happens in browser, spotify, etc with varying degrees of severity, it doesnt seem to be gpu artifacting as it doesnt happen in games at all and it doesnt look like any gpu artifacting ive seen so far
