Retainer Box Makes Combobox Buggy

You cannot use an editable textbox because on a curved UI you get a wrong position on mouse click (maybe the hitbox doesn’t follow the material modified UVs)

Actually, you could try running the following console command:

Slate.EnableRetainedRenderingWithLocalTransform 0

or set it automatically at startup by adding the following into DefaultEngine.ini:

Slate.EnableRetainedRenderingWithLocalTransform=False

This console variable was added in this commit and fixed lots of issues for me related to text boxes. However, for the combo box the only fix was to build my own in Slate and fix the above mentioned issue myself.
