Ok, here is the whole story. I have the problem on WIndows 7 Ultimate running in a virtual machine on Mac OSX 10.9 so both systems share the same graphic card. On Mac v-play works “fine” but low resolution images are not displayed correctly on my retina display due to i guess missing retina support of v-play. So i wanted to try running v-play on a virtualized windows because there i can scale the screen resolution down to something v-play supports.
And so in windows there is the error, which is described above. I am currently working with a external monitor to avoid the retina problems. So on Mac OSX it’s working fine, but it would be nice to get it running on Windows too.
