Known issue: some bright pixel flicker is sometimes visible

[rob040]

When the LED display is used at lowest intensity, some bright pixel flicker might be visible.
This was especially visible in the original software, which refreshed the clock display at maximum update frequency.

It varies very much with display module HW. Some displays show it and some don't.
There were some YT films showing the original Qrome software where it was very well visible.
With lowering the clock update frequency to 0.5 or 1 Hz, it is much less visible, maybe once every 10 to 30 seconds, and the glitches are very short, so a casual user may not observe this.
