WindowBlinds Causing Vertical Black Bar to Appear on Display

September 24, 2026 1:07 PM from

Windows Version Number: Windows 11 25H2 (26200.9550)
App Version: 11.07

I have noticed WindowBlinds 11 causes a vertical black bar to appear on the right side of my screen. It occurs whenever I select or change a theme and remains on there until I restart my PC. Is there an explanation as to what causes this?

I also used RetroBar and thought it was causing it, but after uninstalling WindowBlinds 11, I can confirm it is the latter causing it.

Is there a way to remove the black bar from my display?
