--- Comment #39 from Michel Dänzer <michel at daenzer.net> ---
It would have been better to file new reports instead of adding comments here.

Anyway, please test the patch I attached to bug 97549.

I got regression wtih 1e3218b... (loader/dri3: Overhaul dri3_update_num_back)
on Turks XT/Ni 6670

for

glxgears: ~5600 fps -> ~2600 fps (~50%)

mesa-demos/objviever 'bobcat.obj': 1415 fps -> ~1300 fps (~8%)

and flickering with Blender 2.76b
'User Preferences...' -> 'Window Draw Method' 'Automatic'
Which is solvable by changing the  'Window Draw Method' to 'Triple Buffer'
and is an app bug like Michel Dänzer told in Bug 97059.

All three are fine, again with 1e3218b reverted.
