Screen garbage with blt

It seems that all GTK applications affected except Firefox (which is barely GTK
this days): gtkperf, mysql-workbench, GIMP
If i use Xrender for composting - area where left panel drops shadow sometimes
forget to update.

Also http://ie.microsoft.com/testdrive/Performance/ParticleAcceleration/
results dropped from 24-25fps to 14-15 in Firefox 33.0a1
