Display of 3D surface plot

[克里斯]

Hi ,I had used LabVIEW 2011 for few months without any 3D surface plot problems, but the display of 3D surface plot was abnormal and normal in render window since few days ago.

I've attached imaged that show the problem.

Even other 3D graph plots have same problem. 

I had reinstalled and updated to 2011 SP1, but the problem cant not be fixed.

My PC specs

System: Win7 64bit

CPU: AMD FX-8120

MB: Gigabyte GA-970A-UD3

RAM: 16GB 

GPU: AMD HD7870

Thanks

The problem might be windows update or anti-virus.

Plz try to install labview 2011 sp1 32-bit & 64-bit in your computer to see what happens.

or update computer peripheral drivers.

I reinstalled windows 7 64 bit, latest driver, LV 2011SP1 64bit, and LV 2011 SP1 patch, but the problem can not be fixed. 
When I replaced HD4890 with HD7870, the problem was solved. Maybe it's the bug of AMD driver or LabVEW.
