MetaBackgroundGroup is covering up the top pixel of the panel, preventing click events from activating
I just recently upgraded to F31, including GNOME Shell 3.34, and I noticed that the topmost pixel of the panel seems to be covered by a MetaBackgroundGroup object. This happens regardless of which shell theme I select, including the default. The Activities hot corner still works fine despite the fact that the topmost pixel of it cannot be clicked. It appears that this has something to do with my multi-monitor setup, which looks something like this, involving both a 1080p monitor and a rotated 1680*1050 monitor. Unplugging the second monitor causes this overlap to no longer occur. Although this issue is only a minor annoyance, it is annoying nevertheless so I would be happy to help in trying to uncover the cause.
