I recently bought the Unicorn Hat HD and tested it by running the “lines” script.
I noticed some of the pixels under the diagonal green line lit up, which they shouldn’t do.
They aren’t at full brightness, but definitely noticeable.
Running some other test scripts showed the same problem, it always seems to light up the pixels below in the colour of the one above. So if I turn on a single red pixel, the pixel below will show a dimmer red.
It’s most noticeable with green pixels however.
Does anyone know what the problem could be? Is it software or hardware related?
