[uxa ivb] graphical glitches in the circulating symbol while waiting for an application

Description
This problem affects multiple application. E.g. Empathy:
Connecting to an account takes a while. The process is visualized by two circulating symbols in the empathy window. The normal behaviour should be that these symbols integrate well in the background of the window. But instead of this they have a little black square background (see pictures).
After generating /usr/share/X11/xorg.conf.d/20-intel.conf with the
following content...
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
EndSection
...the problem is solved. This workaround results in little tearing.
Adding the tearfree option doesn't help and results in stuttering.
Anyway: It would be nice to have a real fix instead of this workaround. The driver in Debian is old. Perhaps it exists a fix that I couldn't find.
