Most of the time (~70%) I get rendering issues in gnome-shell immediately after logging in (see attached video). It makes no difference if I have my external display connected or not. Normally logging out and back in (one or two times) solves the problem.

After logging in I change into gnome-shell activities view. If I see rendering issues I log out and in again until I get a normal view – then the problem is solved for the whole session (the problem won't occur after some time).

Sorry, I forgot to mention that this is a regression, I didn't have this problem in Debian stable. I'm not sure but as far as I remember I first encountered these rendering issues right after gnome 3.8 arrived in Debian testing.

The described visual artifacts seem to be caused by a bug in gnome-shell, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=743810

Since this bug was confirmed on many different systems it seems proven to me that this is no hardware specific bug but a gnome-shell bug. So I'm closing this bug.
