I've created a project with the longest display name OpenShift would let me. Then when I go to the application wizard and try to select a project from the combo, all hell breaks loose.

I'm on Gnome with GTK3 and clicking the combo at this point messes up the entire screen to a point that I can't even take a screenshot (sorry I can't show you, it looks awesome). Looks like something overflowing somewhere.

I also tried a bit shorter name, which just resulted in a selection spanning both my screens and beyond.

I think cutting the text at certain length and just adding '...' or somthing like that might make it look better.
