^ That sounds more like a video card problem than a Windows 8 problem. Mind posting the specs (should be in the SystemInformation tab in the MBAACC loader)?
Here are my specs
[ OS ]
Windows 8 64-bit (6.2, Build 9200) (9200.win8_gdr.130410-1505)
[ CPU ]
AMD A10-4600M APU with Radeon(tm) HD Graphics (4 CPUs), ~2.3GHz
[ MEMORY ]
8192MB RAM
[ DISPLAY ]
1600 x 900 (32 bit) (60Hz)
[ DisplayAdapter ]
AMD Radeon HD 7660G
4044 MB RAM
DriverVersion : 8.17.0010.1140
[ DirectX ]
DirectX 11
I'll go update my video drivers and see what happens.
