Description Firlaev-Hans 2021-06-27 08:55:57 UTC

SUMMARY
When you have a "minimize all windows" widget in the panel with adaptive transparency and click it, the panel will become translucent as expected. However, when using a global keyboard shortcut for showing the desktop, the panel stays opaque.

STEPS TO REPRODUCE
1. Have a panel with adaptive transparency enabled
2. Have a Kwin keyboard shortcut for "show desktop"
3. Open and maximize a window so the panel becomes opaque
4. Press the key combination for "show desktop"

OBSERVED RESULT
The panel stays opaque, even though no maximized windows are shown

EXPECTED RESULT
The panel should become translucent when the desktop is shown, just like when using the widget.

[panel] When in adaptive transparency go transparent when in show desktop mode

When in "show desktop" mode window positions are in the same place, but
the stacking order changes.

From a panel POV it's the same as the maximised window being hidden, so
we should factor that into our test.
