hi yesterday I tried to test with all the comic updates and with FarCry 5 at 1080p returning to the desktop screen that is native to 4k did not give me that problem, fatality? I will speak again and let you know...
No, it isn't fixed. What is your display scaling set to for the 3840x2160 resolution? If it's 100% you won't see the issue after resolution changes. The issue is triggered by changes to the scaling percentage. My 3840x2160 scaling is 150% (recommended), and after I play a 1080p game that changes the scaling to 100% during gameplay, the switch back to 150% after the game ends triggers the problem.
My notification icons after gaming (took these screenshots just now):
And then after changing the display scaling to 175% and then back to 150%:
Jason the MS escalation guy left me a voicemail yesterday; I'm going to call him back today.
