http://www.geeks3d.com/20110208/gpu-caps-viewer-1-10-0-geforce-gt-440-improved-opencl-support/ GPU Caps Viewer has several OpenGL demos. one of the demo is GL 2.1 - GLSL Point Sprite Particles. Particles are squares and broken. This bug present in Mesa from 7.11 to 9 for atlest GM45 the program can be run by wine. Tested On: Ubuntu 12.10 Linux 3.5 (both 32 and 64 bit) X.Org X Server 1.13.0 xf86-video-intel 2.20.10 libdrm 2.4.39 Mesa 8, 9 and git Hardware: Intel GMA 4500 MHD (device id 2a42)
Please try with: commit 50a5d5dea0c21886bc3445c0ad0928b03e64ab10 Author: Eric Anholt <eric@anholt.net> Date: Wed Feb 20 14:00:47 2013 -0800 i965: Fix the W value of deprecated pointcoords on pre-gen6.
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 Ubuntu 13.04 Linux 3.8.8 (both 32 and 64 bit) X.Org X Server 1.13.3 xf86-video-intel 2.21.13 libdrm 2.4.46 Mesa 9.3.0-devel (master)

Ubuntu 13.10 Linux: 3.12.0-031200-generic xf86-video-intel 2.99.905 Mesa master: 10.1.0-devel (git-a61ae2a...) Intel GMA 4500MHD (device id: 2a42)
tested with mesa master, works fine on Sandybridge Mobile device id 0116 but not on GM45
