Comment 4 for bug 1927948

First time posting on this forum; apologize in advance if I am not doing this right.

I have the same problem. I have three monitors (1 4k, 2 1080p [1 16:10 and 1 16:9]). 1080p 16:10 monitor is set as primary display, but is Monitor 2 in the physical connections.

Stuff on primary monitor (16:10) stays put; stuff on the 4k monitor and the secondary 16:9 monitor move around.

$ sudo lshw -class display
