I'm marking this bug as fixed in libgl1-mesa-dri 6.5.2-3 then. If you
want the issues with indirect rendering to be tracked, please file
separate bugs against xserver-xorg-core.

Harmless, see https://bugs.freedesktop.org/show_bug.cgi?id=6689 .

Yes, this is necessary due to issues in XAA.

Would have been surprising if it did.

Please post full log files from both versions of
xserver-xorg-video-i810.

These are harmless.
