PTP 2.5 - Interface partly blacked out

Hi,
When I run PTP 2.5, the part of the tour screen that holds the panoramas are blacked out. So are the left and right part of the Style window, see attached screenshot. It seems the functions are there, but I cannot see them, as everything there is black, making it impossible to use. I am also running Autopano Giga, with no issues at all.
What could be the issue? I am running it on a virtual machine with 16 kernels and 32gb RAM, so should have plenty of power, but is noticably faster than my laptop, that doe snot have the issue, but then again, not the power either.
How to fix this issue?
Thanks,
Jake
