I retested with Mesa-git-10.5_git2015.02.04 (using live-usb from http://www.gearsongallium.com/?p=1752), and this solved the issue! Now I don't have any glitches, game runs perfectly with the Intel (OTC) driver.
So this means the title of this bugreport is invalid. Can someone with an AMD card please retest the demo using the live-usb I used?
Since updating mesa solved the issue for you and probably for me (didn't test in older mesa) the bug is more likely upstream and already fixed. Let's wait a bit longer for someone with AMD test.
