I have noticed a ghosting effect and is a bit hard to show on camera. you can only see it at the D line. it could be the mux!!

i really like this library and looking forward to test the next releases. thank you.

Ghosting can be caused by slow register response, a slight delay may be needed. Some panels have this effect, some don't.

Addition: try to add a small delay at D mux line, as it done in PxMatrix
