Not sure if anyone else if having this issue but I have my Xbox Series X attached to the HDMI 2.1 port with 4k120hz HDR, ALLM, and VRR (FreeSync Premium showing on game bar) enabled. Whenever I run games like Destiny 2 or Assassin's Creed Valhalla, I noticed that in the opening scene for those games, my screen gets a really nasty flicker. It hurts my eyes whenever the flicker starts because it gets really bright and sometimes noticed it in Youtube (on the console) whenever I watch HDR content
I am using an Xbox Series X and a 65-inch Q70A. I notice the flicker occurring the most while playing Destiny 2. The issue is especially bad during any sort of transition between activities, transitions before cut scenes, or whenever the screen is black during loading. I have not experimented much with settings to fix the issue.
I have also experienced this issue while playing MLB The Show 2021. The flicker occurs right before loading into a game during Road To The Show.
The flicker never seems to occur during actual gameplay in either game, but it is annoying nonetheless. Especially considering I just unboxed the TV yesterday. Hoping there is a software update to correct this ASAP!
