ivo log with xf86-video-intel of today's git

Oh, right. Yes, that direction makes more sense :)


I've tested today's GIT of xf86-video-intel (which finally fixes my
crashing/freezing X on vt switch!) and discovered that ivo's performance went
waaay down for accelerated applications.

Case in point: Chrome and Firefox. Multiple seconds just to switch tabs. The
browser I'm writing this in is lagging behind my typing about half a minute. I
can see a couple of letters appearing in burst almost precisely each second.

Unaccelerated applications seem to be unaffected, switching off hardware
acceleration in Firefox also helps. But that's just a workaround.

ivo log attached.
