--- Comment #6 from Aaron Sloman <a.sloman at cs.bham.ac.uk> ---
New information: "blt" works even better than "uxa"

As reported in comment 34 in Bug #88584 I had seen a recommendation to use
"blt" instead of "sna" or "uxa", so I changed

/etc/X11/xorg.conf.d/20-intel.conf 

to contain:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option "AccelMethod" "blt"
EndSection

And ran before and after tests using gtkperf. The results showed very
significant improvements, as did ordinary use tests (video in firefox, dvb,
etc.).

There does not seem to be much online information about the "blt" option even
in web pages that explicitly compare "uxa" and "sna" options.

This solves my problem, but the bug that led to the solution remains.
