This is still an issue with F22, and I'd like a hint on where to report it. Which component? Different video adapters are affected. For me it's ATI Radeon. After logging in via GDM, lots of small rectangular areas appear at the bottom of the screen until GNOME Shell apears. They are filled with what seems to be old contents from the video memory. It doesn't look pretty, because it looks like corruption. -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
