You can’t make this up. Microsoft shipped a Windows 11 update yesterday that is supposed to make dark mode more consistent, with dialogs in File Explorer finally getting a dark mode for actions like copying, moving, or deleting files and folders. You get all that, but Microsoft will also treat you with a giant white flash every time you open File Explorer.
“After installing KB5070311, you might experience issues when opening File Explorer in dark mode,” admits Microsoft in the known issues section of its new Windows 11 update. “The window might briefly display a blank white screen before loading files and folders.”
The white flash is like a flash bang if you’re working in the dark with dark mode enabled, and Microsoft says it’s now working on a fix for the problem.
It’s odd that Microsoft didn’t catch this very obvious bug in testing, especially as the company has committed to a more “consistent dark mode experience” generally across Windows 11. The Run dialog in Windows 11 is also getting a dark mode soon, as well improvements to progress bars and charts views, and confirmation and error dialogs.
Update, December 2nd: Removed mention of potential workaround.
