[q35] qt3 renders slowly on dual head

[Nowaker]

Binary package hint: xserver-xorg-video-intel

In dual-head mode (1920x1200 + 1280x1024, DRI2 on) qt3-based applications render very slowly. In Opera 10 a right-click context menu renders in 4 seconds. The same with Twinkle and other qt3-based apps.

After switching to one-head mode the problem doesn't appear.

DRI2 works OK, I can play Enemy Territory when dual-head mode on.

I tried compiling and instaling 2.9.1, 2.8.1 and 2.7.0. The 2.7.0 resolved my problem - everything works perfectly with them.

Recently there has been an update of X-related packages. This crashed my working DRI.

(EE) intel(0): Cannot support DRI with frame buffer width > 2048.

This is even worse than was at the beginning...
