When defining a render file name, or entering a pathway, type-ins literally are invisible. The field remains blank. But moving a cursor around in the field shows it's not blank. The only thing I can think of is the type-ins are white on white. Is there a theme or skin that works around this???

Application menu: "Settings > Theme >" don't pick a "dark" choice that seem to poorly match your Windows theme

Doh... I'm so used to using dark themes in Resolve and Shotcut, I'd forgotten about the choice with KDEnlive. NTL, I prefer the dark theme because it minimizes glare, and helps the elements in the timeline and monitors stand out. I don't see this as just a choice of style or wanting to be digitally goth or whatever.

I'll change the theme. NTL, white on white text remains IMHO a bug that shouldn't have appeared in the dark theme.
