Public bug reported:
After upgrading to Yakkey, I found the graphics performance of my
MacBookPro12,1 (13", 2015, retina/hidpi display) became unbearably slow
- switching workspaces, playing games, even just scrolling web browser
tabs was visibly slower. The computer became constantly warm, and
battery life dropped.
Switching from using from modesetting back to the intel driver fixed
these problems.
