What does help is +**fewer pixels per output**. On a bonnet with more than one output (the +`regular` and `classic` mappings have 3; `adafruit-hat` has 1), put each panel +on its own output and set `parallel` to the number of outputs used and +`chain_length` to the panels per output, for example `parallel: 2`, +`chain_length: 1` for two panels. Each refresh then shifts half the data, which +should roughly double the refresh rate and halve the offset.
