Symptom

After Seelen UI (re)starts with some windows minimized, the tiling overlay shows empty tiles with their border drawn on the desktop: the layout reserves a slot for each minimized window. It stays like that until something forces a re-render (moving a window, toggling the window manager).

Reproduces every time: minimize a tiled window, restart Seelen UI.

Cause

TwmState::initialize adds every window of every persisted workspace to the tree with should_be_managed_ignoring_minimized. That is right for inactive workspaces (the virtual desktop manager hides their windows by minimizing them, and they must keep their slot), but on the active workspace a minimized window was minimized by the user, and it gets a slot anyway.

Fix

Use the minimized-aware should_be_managed for the active workspace of each monitor and keep the lenient check for the inactive ones.

Tested

Debug build on Windows 11, two monitors: minimized Spotify, restarted Seelen; the remaining windows fill the layout and there is no empty tile. cargo test, clippy and rustfmt clean.

Confidence Score: 4/5

The implementation appears behaviorally sound, but the repository’s explicit testing requirement should be satisfied before merging.

Summary

This PR makes startup layout initialization use minimized-aware filtering on each monitor's active workspace while retaining minimized-agnostic filtering for inactive workspaces.

• Prevents user-minimized windows from reserving empty tiles after restart.
• Preserves layout slots for windows minimized to hide inactive workspaces.
• The runtime event path re-adds an excluded window when the user restores it.
• A regression test is still required for the changed behavior.

I confirm, I constantly encounter this problem.
