video glitching when Mission Control and Apple TV enabled

One week old 16" Mac Book Pro / M2 Pro was replaced due to video glitching when Mission Control was enabled and while using Apple TV. Took the week old computer back to Mac store and the friendly staff exchanged it after I was able to replicate the issue while at the store. Seems that if you enable MC (mission control) and Apple TV at the same time, and you minimize Apple TV, it creates a rapid flickering effect on the display - particularly over the minimized Apple TV icon. It will also do rapid flickers on the edges of other open windows. The top menu bar will turn a Hot Pink and alternate between that color and its normal color. This second computer (replacement) does the same thing! I just finished setting it up and tested MC with Apple TV and , sure enough, flickering like crazy. Another issue I noticed on both brand new Macs: when watching videos, the black levels are waaaaay too dark (specially during dim lit scenes) this is both true for Apple TV and YouTube videos. 2 out of 2 is way too much of a coincidence.
