Since Wednesday, I've done as follows: - Upgraded to mutter 3.21.91-2 and gnome-shell 3.21.91-1 (repaint/redraw issues). - Tried to report the bug, but reportbug showed a version of mutter in unstable. - Upgraded to mutter 3.31.92-1 and gnome-shell 3.21.92-1 (repaint/redraw issues). - Reported the bug. - Downgraded to mutter 3.20.3-2 and gnome-shell 3.20.3-1 using dpkg and /var/cache/archives. - Upgraded to mutter 3.21.91-2 and gnome-shell 3.21.91-1 again (repaint/redraw issues) - Tried some DRI suggestions from ArchWiki, but none of them solve the issue. - Downgraded to mutter 3.20.3-2 and gnome-shell 3.20.3-1 using dpkg and /var/cache/archives. - Upgraded to mutter 3.21.91-2 and gnome-shell 3.21.91-1 again (repaint/redraw issues) - Tried disabling some files in modprobe, but it doesn't seem to solve the issue. - Downgraded to mutter 3.20.3-2 and gnome-shell 3.20.3-1 using dpkg and /var/cache/archives.
So the problem is always reproducible. -- John. > Am 14.09.2016 um 17:16 schrieb JWM: > > > > > After upgrading my system this morning and restarting a new gnome- shell session > > > > (by rebooting), everything being displayed fails to repaint properly. > > > > > > Everytime I launch an application and try to move the window it leaves traces > > > > (i.e., shadows of its previous positions).
