I'm convinced thats the issue something to do with missing drivers, no idea how to fix it though??
No ideas. Such issues either involve fixing specific drivers (usually when you have an idea, such as weird colors pointing to video drivers) or reinstalls of Encore or the OS.
I'm PC, and no help for this issue with my own experience or testing.
With no support for Encore on new OSs, I want the forum users to get any useful info out there. Not too much so far.
