I find this with any theme I use or font, the button's BOLD font makes it cut off inside buttons. If it's normal, then there is no problem. This is not just RNORadio ( example screenshot ), but any application.

I've tried playing around with MUI by setting the borders of the button, but nothing seems to fix it. Any idea on how to fix this?

The only way to fix this for now is not to use soft styles in MUI settings - so don't select Bold in various Font settings for MUI controls. I'll hopefully figure out a fix for 3.16...

Thanks jaca for the reply and tip!
