Host: Mac Pro 5,1 6-core with AMD Radeon R9 280x running MacOS 10.10.5 Guest: Fedora 20 i686 up-to-date with latest Parallel Tools installed Parallel Desktop 10.2.2 (29105) Run "glxgears": the window is black instead of showing the infamous 3 rotating gears. Other OpenGL apps I have tried do not work either but glxgears is the easiest to reproduce the problem. Any idea? Thanks in advance.
