Slow, jerky animation in Full Screen preview

[HScottH]

Greetings!

I am a new user, and I love Dexpot!

I run this on my office PC, which uses two 1920x1200 monitors. It works perfectly.

However, I use my home PC most of the time, and when I switch to full-screen preview, the animation takes perhaps two seconds (and looks very jerky) entering the preview, and perhaps one second returning.

I suspect this is because I am using 3x UHD (3840x2160) monitors.

I saw a forum post from perhaps two years ago asking for a way to disable these animations; was such a fix added, or is there a work-around?

If you are interested in other specs:
CPU: Core i7 980x (6-core)
GPU: 2x AMD R9 280x (display-port, 60hz to the monitors)
RAM: 24GB triple channel GSkill DDR3 (about 24 GB/s throughput)
Display: 3x Samsung U28D590D UHD monitors
