Hey all/ Help?

[Infinaut]

not sure if this should be here or in Technical Discussion, but i was hoping someone could help me with a UI issue? Or point me to the right place to find what i need to sort it myself.

Basically my UI/ all options and settings windows are completely transparent? to the point where if i open a tab or something with a drop down menu i can't read the text because it overlaps with whatever it dropped over. There doesn't seem to be a background to any of the windows. (opacity sliders didn't help)

I thought this was normal until i watched someone else playing

thanks
