enable dithering for all devices

[Kas152]

Hi,

As usual, many thanks for creating this fork of Prismatik! It is really the most coprehensive program out there. I just have one request about the dithering, there is an option to turn it on or off beacause not all devices react properly to it. This is a known issue. It creates flickering of the leds on some devices, mine included, but the colors are much more accurate. Is there a way to make it work on all devices, or is there something I can do myself to fix this? Many thanks in advance!
