vesa cpu pegs

Description

Created attachment 114581 Xorg.0.log

Since https://bugs.freedesktop.org/show_bug.cgi?id=89353 was fixed, I'm now back up with Xorg7.7 and vesa..

A serious performance problem is encountered when trying to drag a window around on the screen, in particular when there are a few already displayed. A good test was to put a terminal up running 'top'. EXTREMELY slow and top shows Xorg running at around 100% on this single core x86 machine running TinyCore (linux 3.16.6).

This was reproduced there on different machines: http://forum.tinycorelinux.net/index.php/topic,18090.msg110553.html and a quick look around the internet with "xorg.7.7 vesa cpu" search terms finds numerous problems of this sort.

I tried both without and with GL, but it makes no difference.

Attached is an Xorg.0.log
