I don't have this issue in Ubuntu 18.04 with the same graphics card, please try to use the latest build of Blender 2.8 and Load Factory Settings for a clear blender startup file.
Then try to open the blend file with Load UI disabled like in the screenshot below.

Maybe not related to the bug, but I get an assert when I try to open the file.

Looks like the versioning code is wrong.
Or the file is broken...

Looks normal here on Mac. Although the layout is clearly from 2.49x and earlier.

I do remember this dice tutorial for old Blender versions: https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/Die_Another_Way

The original file is probably a fair bit older than 2013, so it might be an issue with opening very old blend files (Perhaps Blender 2.0 to 2.4 era)

This is the latest version of 2.8 downloaded immediately before posting from the blender website. And I noted that I did load factor settings before trying again....

@WilliamReynish
What version of macOS are you on?
And what version of Blender did you use?

Yes, the file is definitely older than 2013 (2009 or 2010 I think?).

So that assert posted by @JacquesLucke pointing at the version reading code may well be a relevant clue.

Seems odd that an old (or even corrupt, though I don't think the file is corrupt) file could cause the UI to freak out so badly. That's definitely a bug that would like to get fixed. Some kind of better error handling or something so that a "bad" data file can't corrupt the app seems important.

That said, I'm unfortunately not in a position to get the source and dig into the code to find the issue and offer a fix (got to be a huge code base).

@WilliamReynish that is likely the tutorial my son was working from when he created this. Nice find.

The UI font issue seems to be resolved in the latest beta (blender-2.80.0-git20190611.8aa87972cac3-x86_64).
