grabScreen Error (unkown OF pixel format)

Hi,

Now, I’m trying to grab a screen by ofImage grabScreen.
However this way is not woking actually with following error.

And created window was still white with loading icon, despite I set the background color black.
It seems to hung up in grabscreen process.

My current environment is

  • Surface pro 3
  • Visual studio 2015
  • oF 0.9.3

( what should I put another information to solve it ?)

Thanks.
