Hello,

Many thanks for your reply. As you suggested, I've tried with Mesa from Git
master, dated May 1st (10.2-branchpoint-2-g829cb04). FlightGear 3.0.0 has been
running for a significant amount of time (I'd say 6 to 8 hours), with quality 5
for several hours and I haven't seen any bug from the graphic stack (well,
there are weird rainbow-like textures in a few places, but I've been seeing
them for several months already and haven't been able to investigate yet; it's
probably unrelated to the bug being discussed here).

I'd like to say that the performance is also much better than with the graphic
stack available in Debian wheezy. Yay!

Part of the actual testing in FlightGear is done by my nephews on weekends,
therefore I can report with a longer testing period in 1 to 3 weeks
approximately if you wish.

I have two little questions:
  - is there a performance impact if mesa has been compiled with
--enable-debug?
  - when it is rebuilt, is it necessary to restart X.org in order to have
everything using the new libraries (I have used the method outlined at
http://pkg-xorg.alioth.debian.org/howto/build-mesa.html to test the new mesa
without messing with the system installation---in short: LD_LIBRARY_PATH,
LIBGL_DRIVERS_PATH and EGL_DRIVERS_PATH)?

Thank you!
