Hi all, I've got two 12 volt WS2811 strips hooked up to a RPi2 via a level converter on GPIO (18). Controll and grabbing works fine, until the light should be dimmed, then it just goes crazy. Best example is when I use the color wheel. Full brightness gives all the right colors, also sliding to white. But when I try to dim the light (even a little bit), some parts of the strips turn another color, fully on. Depending on which color I try to dim, they turn blue or green. And when the light should be completely off, they still give very dimmed red light, with some parts still blue or green. Also when using effects which should have some black parts, the lights stay very dimmed red.
I think I looked at every configuration that could have influence, but I can't find any. And I think it's a software issue, because full brightness works fine on any color aswell as effects which give full brightness like rainbow swirl and solid police lights.
On LibreELEC there is one screensaver however that gives correct results with parts of the LED strip turned fully off like it should.
I added three photo's showing the results. Showing red fully on (no errors), the screen saver with some parts off and some parts on (no errors), red slided to black, but instead shows dimmed red and a part green instead. The other LED strip goes even more berserk with most parts green.
Here is my hyperion configuration:
