Maybe this problem is related to mesa demo pointblast. Which renders squares instead of points.

Tested on:

Ubuntu 13.04
Linux 3.8 (both 32 and 64 bit)
X.Org X Server 1.13.3
xf86-video-intel 2.21.8
libdrm 2.4.43
Mesa master from git

Hardware: Intel GMA 4500 MHD (device id 2a42)

the mesa demo pointblast renders fine with gallium swrast driver but not with gm45 hardware renderer. still present in the master

tested with mesa master, works fine on Sandybridge Mobile device id 0116 but not on GM45
