White Screen when running Mantel

White Screen when running Mantel
Logged in to Steam started Star Swarm ran D3D no problems other than not utilizing both CF GPUs.

Using default settings I:
Click to run Mantle and screen goes immediately to White
However Processor and GPU Utilization increases as expected
as if it is running in the background of this white screen
not sure if it would run the full 360 seconds
Ctrl+Alt+Delete end process

System specs:
Recent clean Install Win8.1x64 Pro (All Current)
4770k @ 4.3 (STABLE)
2x Ref 290x (14.12)(Stock Clocks)
16GB 2x8 2400 DDR3 XMP1

I myself had issues with the demo/benchmark.  Tried re installing driver, etc...

Found the issue for me was running two monitors.

 

R9 285, port 1 HDMI, secondary display LG LCD monitor @ 1280x1024

R9 285, port 2 DVI, Primary display Samsung 245BW LCD monitor @ 1920 x 1200

 

Primary display would white screen under Mantle when launching Star Swarm.

 

Disabled secondary display (LG monitor) and launched the demo under Mantle and the demo ran properly.

Don't know if the Dev's even look at this forum, but if they do please be aware of this issue.

I use the 2nd monitor to monitor system wide statistics temps voltages etc not being able to use it like every other benchmark is simply unacceptable. If they had taken the time to support the product I might consider it's use again but it's lost to me now. Even with the advent of DX12 bench anything they offer is crap ware to me.
