I’ve noticed that some faces with white or grey backgrounds have a noticeable flicker in active or AoD mode. Similar to when video recording an old monitor and the refresh rates don’t match the video frame rate, if that makes sense.
For example:
TSM Chronograph
GRR M900
RZ 168 Classic
Tried resetting the watch, removing and replacing the faces, etc. They consistently have trouble.
Yet others are perfectly fine.
