Description of problem:
Fedora 33 has changed the appearance of non-active windows in gnome shell, so that these windows appear in a "greyed out" state (which looks a little like the window is disabled).
Unfortunately this breaks Qt applications which use dock widgets (QDockWidgets), as all docks in an application appear in this "disabled" appearance, even when the main application window is focused.
Version-Release number of selected component (if applicable):
How reproducible: always
Steps to Reproduce:
1. Install a qt application which uses dock widgets (e.g. "QGIS"), run on Fedora 33.
2. Note that appearance of dock widgets (such as those which show on the left of QGIS by default) will appear disabled until a click is made within these.
Docks only appear enabled after a click, and only a single dock ever appears enabled at a time.
Docks should appear in the "active"/"enabled" appearance whenever ANY widget or other dock in the parent window is focused.
