The monitor is a Dell UP3214Q connected to one of my NVIDIA graphic cards via mDP 1.2. The first half of the video the monitor is set to SST mode. The second half of the video the monitor is set to MST mode (60 Hz).
While in SST mode the drop-down menu for the Firefox bookmark "star" and various other add-on drop-down menus work just fine. Click on the icon and the drop-down menus are displayed.
However, when I switch to MST mode the drop-down menus shown in the first half of the video will not be displayed correctly. In fact it appears that they're simply not being rendered at all but. However, if you look closely (you might not be able to see it in the video) the drop-downs are actually working, they're just opening and closing in a fraction of a second. This only occurs in MST mode.
Early adopters for the win! Can someone at Dell kindly assist?
I didn't find the right solution from the Internet.
