GNOME Bugzilla – Bug 752934
css: shadow paints above border of the container
Last modified: 2021-07-05 14:17:35 UTC
You can trigger the bug putting a button on the bottom of a rounded square container with borders (3px or so). Then make the button active (which uses box-shadow: none), and the background of the button is painted above the border of the rounded square. This is a common case for dialog buttons style. For now a workaround is to, in the active state styling, use box-shadow: inset 0 0 black instead of none, which goes through a different code path that works correctly.
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/ Thank you for your understanding and your help.
