I did not receive an update for gnome-shell or gnome-shell-common, as rphair did. Not sure why.

After logging off and logging back on, all Gnome windows behaved as expected. I WAS able to click on windows and title bars to bring focus to that window. However, I noticed that windows from snap packages DID NOT behave as the native Gnome applications. The same incorrect behavior still occurs with just those applications. The only exception to this has been the snap package of Firefox, which somehow has always worked correctly (meaning that with mutter-43 I could click on the title bar of a Firefox window to bring it into focus).

I've noticed these application windows exhibiting the correct behavior under mutter-44.1:

gedit
nautilus

These snap applications DID NOT behave correctly:

Again, the snap package for Firefox continues to be fine?

Thanks.
