Mouse Cursor Rough Movement

I was just checking out Preferences and I was set for ‘Ultra High Quality’. I set rendering to ‘no antialiasing’. I’m back to normal mouse movements and all the laggy/choppy movement is gone. I will look into some of the Ubuntu forums I frequent and see if I can glean any answers. I probably should go to a low end Ati/Nvidia graphics card. I’ve had problems with Intel HD in other programs. Thanks for the input!
