Help!! my new P3 64x64 1/32 panel
shows in the first (white) and second line (yellow)
the right colors, line three should also be white but purple and line four should be yellow, but blue.
SmartLed shield V4 is used
// only for testing

const uint8_t kMatrixWidth = 64;

const uint8_t kRefreshDepth = 24; // known working: 24, 36, 48
