No noticeable difference with you patch. BTW I did repeat bisecting and it
again showed commit c298bab60ea63882f34825a35cbc60f662783e64 as the one
introducing this slowness. So indeed your analysis in comment 17 looks right. I
wasn't able to bisect any further slowdown with glsl2 merge which Sven
mentioned in comment 24. However we might have different setups because for
example I don't have any troubles with libtxc_dxtn.so
