Which devices did you test?

Rg35XX Plus with Funky Jacaranda. 100% works and solves the horizontal lines issue. I believe it works on the RG35XX H and Pro as well, since they use the same panels (640x480px 3.5").

Excuse my ignorance, but where do I enter these values? I’m having this problem with my RG35XX-Pro.

Excellent! Now tested with the Plus and the Pro. I hope this will be fixed in the next version of muOS.
