I am using Ubuntu 10.10 on my acer laptop. hardware config: Intel i3, 2GB DDR3 and onboard Intel HD graphics. I installed alpha5. On all the maps, I see these strange red squares around some buildings, mines and quarries. I updated the kernel and the xorg drivers I even tried compiling the source code. The squares persist. I have an old desktop with ati xpress200 onboard graphics..I had installed alpha 5 2 weeks ago. I doesn't seem to have this problem on it, though the game run slow on it. i have attached a screen shot. i have observed the same problem in the other maps too. and thnx rasunadon
