Desktop artifacts/graphical issues
SUMMARY
I was playing Baldur's Gate 3 and CS2 today while having Night Light on. I have
noticed that the desktop became sluggish while playing BG3 and seconds later,
the whole entire desktop, along with some Electron programs (Discord) started
having weird graphical issues.
After trying CS2, everything was fine except the Steam that overlay started
being extremely sluggish and having weird graphical issues.
I have attached an image of the graphical issues.
STEPS TO REPRODUCE
1. Open a game on the NVIDIA GPU (as of now, I have found that the desktop
graphical issues only happen with BG30
2. Leave the game running for a while
3. Tab out and try to use Discord
4. Notice how after a while things start to go crazy
5. All of these while having Night Light on
OBSERVED RESULT
Upon turning off Night Night, while playing BG3 the general sluggishness of the
desktop went away along with the artifacting of the desktop and I have have
noticed that CS2 gained 100fps compared compared to when I had Night Light on.
EXPECTED RESULT
Desktop and general performance should not be impacted by this.
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
