Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

• Meshtastic UI aka MUI colorTFT
• InkHUD ePaper
• OLED slide UI on any display

Firmware Version

2.7.15.567b8ea

Description

I have a WisMesh Pocket V2. (Site: https://docs.rakwireless.com/product-categories/meshtastic/wismesh-pocket-v2/quickstart) The web flasher auto-detects "RAK Wisblock 4631" for flashing the firmware.

This version of the firmware shows the UI with the first column on the OLED being what should be the last column of the OLED. Imagine shifting the whole UI over one (or maybe two) pixels to the right, then pasting the column or two of pixels that would "fall off" the screen on the left side, except shifted down maybe 8 pixels.

It feels like there may be an off by one byte error in drawing the screen. (I've used other I2C OLED screens where the screen draws 1 8 vertical pixel "row" at a time.)

Thanks for taking a look!

A fix that has worked for me:

In the display settings change the OLED definition from "OLED_AUTO" to "OLED_SSD1306".

This is the correct advice.
