Some glitch with "r" symbol in text

I use AppImage build.

I tried with latest AppImage release (the last stable, 0.02) and could not replicate the issue.
Is it happening from a fresh start or do you need to play first or this to happen?

Is it happening from a fresh start

Yes. I has same issue on fresh install Stunt_Car_Remake-7476936-x86_64.AppImage
