Public bug reported:
The patch from bug 1764558
(https://gitlab.gnome.org/GNOME/mutter/merge_requests/62) is broken, and
should be reverted (or fixed). The breakage it introduces is noticeably
more severe than the tiny shadow it fixes.
The broken patch resurrects bug 1718238, which was fixed not long before
Bionic's release (but then subsequently broken). Details about the bug
re-occurring start at comment 17 of that bug. Screenshot in comment 26.
Quick recap:
- Launch Ubuntu's default desktop (on X11).
- Go to GNOME Tweaks -> Top bar -> disable Application Menu.
- Make sure the gnome-icon-theme package isn't installed.
- Start gnome-terminal -> note that it looks as in the aforementioned
screenshot.
For some (unknown) reason the removal of the supposedly irrelevant
gnome-icon-theme package makes GTK+ place an icon of 48x48 size as
_NET_WM_ICON, rather than a 16x16 one as when this package is installed.
Mainstream mutter scales this image from 48x48 to 16x16 and then
displays it, as desired. The faulty patch removes the code that scales
the image, so the 48x48 version shows up where there's only room for
16x16.
