Expand Lens button is not changing by Windows UX standards

[SignFinder]

Hi team,
The visualization of state in Lens is not changing despite expanded\collapsed state.
Lens 2026.4.151333-latest, Windows 10 X64 LTSC.
It is standard for WIndows UX that in the case application is expanded to all screen - button should be in the form of two superimposed squares.
But in Lens there is one square button in collapsed and expanded status.

Hi @SignFinder,

Thanks for the report -- and for the screenshot, that's exactly the right reference. We already have this tracked internally; it's a sync issue between our custom title bar and the actual window state on Windows, where the maximize/restore button doesn't switch between the single-square and stacked-squares glyphs as Windows UX expects. No fix has landed yet, but it's on the list. We'll update this thread once one ships.
