Is the fps counter broken for anyone else?
I enabled it from the onscreen display > onscreen notification > display framerate but it doesn't seem to work, it's just stuck at n/a.
Ditto, for weeks. But only on 2D cores. PSX and N64 FPS work.
Try the latest nightly.
I think that got fixed yesterday or Wednesday, but try today's nightly to be sure.
I've tried multiple nightlies to no avail.
What menu theme are you using?
Try with others.
If it still happens, try backing up your .cfg file and let RA make a new one, see if that does.
If not, then simply restore your .cfg, and report the issue here, please:

Ozone. And I started from scratch when 1.78 released. Still no dice. Odd, very odd.
