"i945" is not a "driver", it's a chipset family.

It does appear that all commenters on this bug have i945 chipsets. The correct command to run to check this is:

 $ lspci | grep VGA | grep 945
 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)

It may say "945GSE", or "82945", or etc. The key thing is that "945" is in there somewhere.

I tested a i945 netbook, first with Ubuntu from about a week or so ago, then updated to current. Prior to the update I could not reproduce the bug. After the update I was able to reproduce it.

There are three drivers for i945: One is the kernel driver named i915, one is a mesa driver , and one is the X driver name -intel. The kernel driver handles the hardware, the mesa driver does 3D acceleration, the X driver 2D acceleration.

During this period, none of the three drivers have changed. mesa's last update was 27 Mar. xserver-xorg-video-intel was 15 Feb. The kernel has had some changes more recently but has been frozen in this time period.
