LED sporadically flash in a different color #87

If the display is set to red (others haven't been tested so far), flashes of a different color will appear sporadically - blue mostly, but sometimes green flashes have also been observed

The RGB LEDs are controlled serially at 1 MHz. Due to the high number of tasks running in the firmware, data transmission errors occasionally occur. The RGB LEDs are controlled cyclically, so the errors only occur for a short time.

As a solution, the cyclic control could be replaced by an event control when the state of the LEDs changes. This should stop the flickering.
