XBMC UI flickering screen

Hi all, newbie here hoping someone out there can help me troubleshoot this issue of the UI flickering intermittently. I'm running XBMC v11 Eden on Windows 7 32 bit, graphics card is Intel Graphics Media Accelerator 3600 Series - I've tried updating the video drivers, and playing around with resolutions but still no luck.

Debug log is here:

Thanks in advance!
