Lightroom CC

Hello,

I have a 15-inch Mac Book Pro (2.6 Ghz Intel Core 7 16GB Memory, Radeon Pro 450 2048MB Intel HD Graphics 530 1536MB) and 2 monitors plugged in on 1 Eizo CG241 W and an ultrafine LG 5K.

My problem is that lightroom randomly jumps from screen to screen.

Someone would have an idea to fix it?

Thank you in advance. Have a good day !
