Description

Issue type

enhancement

Which version of the app?

WinUI 3 Gallery

Description

On small monitors/laptops etc, the launch window default size is probably acceptable. On larger monitors (ultra wide for example) it is massive, 3824 x 1002.

Request that a max size is set 1366 x 768, or that it remembers the size it was last set to (like UWP did).

Research direction

Start by finding the WinUI 3 Gallery application's startup and main-window initialization entry points. Check how the window currently receives its default size and whether any existing persistence pattern is available; done means the launch window is capped at 1366 × 768 or restores its previous size, with the chosen behavior verified on a large monitor.
