Parallels 10, Windows 10 Tech Preview, bad fonts

Hi all. So on any "Metro" type screen (not traditional desktop) the font rendering is either broken or... well, something. Screenshot attached.

Anyone else seen this problem or have an idea for a fix? I tried reinstalling Guest tools. This issue occurred after the preview build updated itself to build 9879.

Thanks!!!

 

Configure your VM to use DirectX9 instead of DirectX10
