Describe your issue

Window borders don't show up on the current version of UniGetUI.

(This screenshot is only for demonstration. On my machine this setting is turned ON)

This is a regression introduced during the transition to Avalonia. The WinUI version by comparison:

Keep up the good work. The Avalonia UI is definitely getting closer and closer to the previous platform.

In UniGetUI 2026.2.5, even in "full screen" mode a quite thick empty border appears. Accent colours on or off doesn't fix that. Sometimes it decides it's a tiny empty border, sometimes it decides its an even thicker empty border 🤔.

For example, more border:

I think every time I close it with the X in the top right. And start it with the UniGetUI icon next to the clock. The border grows.

I think a screen standby, with the window open, also increases the border area.

Wouldn't surprise me if that 'column label cut off' bug has a similar off-by-one accounting bug that accumulates.
