Display: Can only select one display

[Salem]

If i have two screens connected to my computer, after selection one in "Display" (clicking on the screen image) i cannot click on the second display image. Also sometimes i can click on the first screen image and the second, but cannot click on the first again.

If i go back and select "Display" again, i am able to select the other display and configure it. Also, if the window losses the focus and gains it again i am able to select other display. Despite not being anything very important is very annoying.

How to reproduce:
1- Connect a second display to the computer;
2- Open "Display" settings;
3- Click on both screen images alternately (screen1 -> screen2 -> screen1 -> ...)
