Screensaver turns into white dot

Firmware used: 1.1
Active mode: Spectrum

I noticed it twice in the past two days. At some point the screensaver only displays a white/orange dot that always starts in the middle of the display. Then it moves to the left edge and turns into white. When there is audio in the room again the normal display continues. Here is a video of the effect: here
It looks a little bit like the four normal dots of the screensaver (green, blue and red) have the same location for some reason and then the resulting combined color is white?
Soft power off (two fingers) does not help. After a power cycle and reboot it is back to normal operation.

Sounds like a millis() counter problem, I'll have to investigate the screensaver code! Your hunch is correct, the white dot is when all 4 colors are overlapping and not splitting back up. Thanks for the tip!
