Description:
I’m using KDE Plasma 6 on X11. I regularly use the “shade/unshade” window feature via mouse wheel on window titlebars. This feature is extremely useful to keep windows in place and out of the way without minimizing them.

Since upgrading to Plasma 6, I’ve encountered the following issue:

    A window is shaded via mouse wheel (or right-click > Shade).

    If I move the shaded window by dragging it, it becomes impossible to unshade it normally.

    The mouse wheel, right-click menu, and keyboard shortcut all fail to unshade the window after it has been moved.

    Only workaround: resizing the window manually, which forces it to redraw and restores its normal state.

This is a regression compared to Plasma 5, where the behavior worked as expected.

This functionality may be considered "niche", but it's a long-standing and powerful feature for advanced window management. It would be great to see it maintained and fully functional under Plasma 6.

Steps to reproduce:

    Shade a window.

    Move the shaded window.

    Attempt to unshade — it fails.

    Resize the window — it unshades.

Expected behavior:
Shaded windows should be unshadable regardless of being moved.
