1.Do you see the issue on WB style such as Acrylic 7, Arcenic.. etc?
Windows 11 Home 23H2 (OS Build 22631.4269)
Start 11 v2.11
Turns out the problem doesn't appear on all "blinds". For instance, Acrylic 7 and Aero 11 display properly, however Alienware and Allegiance have the white border. I'll upload more screenshots tomorrow.
