OpenGL working on external monitor but not in built-in scree

Post by vmo-mac »

I'm using an ubuntu 12.04 LTS on a MacOS (Yosemite) host and using an OpenGL software that runs smoothly when the guest system is moved to an external monitor, but very slooooowly when using the built-in screen of the MacBooK. I'm doing something wrong, but I cannot figure out what, any hint? Thanks.
