I notice a slowdown of Studio. Basically unworkable. Rotating a view is hardly possible.
Anyone with a tip or is this a bug ?

iMac 5K Skylake i7 4Gh.
OSX El Capitan
iMac 5K 8Gb ram, GC M395X 4Gb. Ram will upgraded this week to 24Gb.

I just noticed it might be because of missing background image files and not related to the specific system or hardware. A fresh mxs model file without any images was no problem at all.
