Dear Maintainer,
On my gnome desktop, I installed the dash to panel extension,
Desktop Icons NG (DING) extension, AppIndicator and KStatusNotifierItem Support extension, and then opened a series of windows such as virtulabox,
file manager, text editor, browser, command line window, etc.
in the background. Then sometimes when I switch back to the desktop, or
other times, different windows will overlap.
The expectation is that at any time the window will not overlap with
other windows to form a single window.
