Has anyone else seen this or know why this happens? When your cursor is hovering over the battery icon on the taskbar a very tiny white window? appears above it. Is this just a bug to be worked out? Its in the red circle

Can not reproduce this on Canary build.
Report it in the Feedback Hub and use Recreate.

2025-12-23T19:17:36.7566667+00:00 Yes I do and it's on.
What I don't have is the colored battery icon.
