GUI problems [solved]

Does anyone else have the same issue with GUI elements?

For some reason buttons like "Done", "Back" and "Cancel" are placed in the wrong place, overlapping text and input fields.

Worked fine all the time before. Have not changed anything. No new installs or updates.

Update:

Of course I tried to re-install and have up to date drivers.

Update 2:

Thanks to Ashley! If anyone has the same problem please see a working solution in Ashley's post below.

Try pressing 'Reset dialogs' in Preferences.

Thanks, it works again :)
