Wrong Transparency of Right Panel in Top-bar
Hello, I am facing a visibility issue with the right panel of the top-bar in Gnome Shell 3.30.2. The panel gets wrong transparency when I trigger the transparency switching of the top bar, e.g., by moving a window close to it, where I would assume the whole top-bar to be fully transparent.
However, the issue only occurs in a specific monitor setup. So I have two screens of different size. When I arrange both screens so that their top edge is on par, the bug does not occur. But when I re-arrange both screens so that their bottom edge is on par, I can trigger the bad transparency of the right top-bar panel. In this case, you also get some transparency flickering when you trigger the transparency switching of the top-bar
I think the bug occurs because in the first setup, the virtual workspace on the right starts with an empty and black area which seems to affect the adjacent top-bar right panel on the left workspace.
I attached four screenshots which illustrate the issue.
