Probably unrelated but similar issue, though _without_ SNA (having an 
intel 4500MHD, using rawhide): sometime after mid-july I have started 
suffering severe redrawing issues, see [1] and [2]. Unfortunately I 
spent a few weeks working with the discreet graphics, so I missed the 
version after which issues started appearing. I am now gradually testing 
older xorg-x11-drv-intel packages to try to identify when breakage 
started, I suspect it is sometime after 
xorg-x11-drv-intel-2.20.0-1.20120718.fc18. Issue appears only after some 
time, and is definitely an intel issue (switching to the AMD discreet 
card it works fine). Also, GTK applications are affected much more 
severely than Qt ones. I was hoping to gather more information before 
filing a bug, (at least which version causes the breakage) but since 
this was brought up, here it goes...
