The 0.9.12 release was big, so it's not surprising that a couple things slipped through. 0.9.13 was released to fix two things:
- Some users with lower resolution displays had scaling issues
- A device setting wasn't properly saved for Marlin users
It's also possible that you will have to manually download this version, as there was an issue with an incorrect SSL library version being included with 0.9.12, meaning that the automatic update check might not work.
