I am running the Gnome desktop. Any ideas? I think it's the same problem as we had with xorg-x11-server-Xorg-1.15.0-36 and Ferret/R etc. I posted a message here at 16.09.2015 with subject : "rePost : SL6.7 problem with ferret/R and xorg-x11-server-Xorg-1.15.0-36" about this problem. For the moment a) the solution is a downgrade to xorg-x11-server-Xorg-1.15.0-26 b) we know that the problem is that "updated Xorg server does not send the initial "expose" events" (thanks to Konstantin Olchanski) c) And we know that the problem comes from 1.15.0-32 update (Fix backing store's Always mode). I sent a mail to Adam Jackson ([log in to unmask]) the person who applied the 1.15.0-32 version... But I have absolutely no reply from him... :-( Thanks, Paul Zakharov
