I don't know exactly the cause of this issue. Some possible reasons are: 1. libva driver handles a small drawable wrongly. 2. libva driver gets wrong parameters from X server. 3. X server swaps front/back buffer wrongly for a small drawable. If possible, could you give a try with the latest X server and xf86-video-intel ?
