Hi,
I recently finished my new HTPC box, using an i5-4570T. I'm also getting these graphical corruptions using the latest XBMC 13 nightly build, Windows 8 Pro x64 and the only officially available driver from May 2013 - the rest works just fine.
After installing the beta driver 15.33.64.3214 from June 2013, the graphical corruption's gone. But I can't hardly playback any file, because no sound is getting trasmitted to my av receiver randomly, the video's playing choppy with low frame rates and sometimes XBMC suddenly crashes. Checking the debug log shows a LOT of strange errors all the time. This does not happen when using the May driver... Reverting fixes all this, but I have to live with the display bugs again. :S
So please, Intel, could you release another beta version for HD4600, in the hope I could achieve a satisfying user experience? 4th gen users are pretty much up the creek right now...
Thank you, greetings from Germany,
Jonas
