Issue: Oringally thought an issue with the mono display where had to adjust the size of the screen from 122 to 127 to be able to use the whole screen where rows at the bottom where not updating and then had to adjust when drawing text and shapes with displayio by adding an offset on the y-axis. Have since tested both the mono and and tricolour featherwings with the exmaple code for the SSD1680 (exmaple syays it is for the tri colour one) and both have the same issue where there are rows are the bottom not getting updated and looks like the top it not aligned (see picture below). Looks like could be an issue with https://github.com/adafruit/Adafruit_CircuitPython_SSD1680. I dont have any alternate feathers to see if it just this feather type or the code.
Ya, as @makermelissa said on the PR. I think this is an incorrect colstart or rowstart value. Setting those will shift the data written to the driver IC memory.

Added column_corection argument to ssd1680 to set colstart so can be adjusted in simpletest to fix issue adafruit#10 and can still work with previous sampletest file if needed as only tested on ESP32-S2.
Feather: Adafruit CircuitPython 8.0.0 on 2023-02-06; Adafruit Feather ESP32S2 with ESP32S2 (4M Flash 2M PSRAM)

Exmaple fix for example file on pull request but seems like a work around now - #9
Picture of the tri colour display (look at bottom and top rows):
@tannewt relating to pull request #9 but looks like the issue is not with the exmample file.
