Likely a graphics driver issue ...
Yeah that looks like a glamor bug ... would be worth testing with xserver 1.17 (like with F22 Alpha) if you can reproduce it.
In F22 Alpha this bug preserved. https://www.dropbox.com/s/q158aseqqeoqyh8/Fedora22alpha.png?dl=0
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.
