Update your graphics drivers and configure them suitably and/ or check the relevant hardware acceleration settings in the programs.

enurz,

What happens if you Ctrl/Cmd+E (Illy speak)?

This is what GPU is about:

Graphics cards are included in the system requirements:

Apart from an inadequate card, the issue can be caused by lack of driver updating, lack of proper recognition of the card by the computer, and whatnot (including rifts in the space time, moon, weather, and the fact that Illy sometimes moves in mysterious ways).
