After installing the latest Klipper, I too have a garbled display with offset characters, running on a stock Ender 3 Pro. The printer contains a version 4.2.2 board with an STM clone (GD32F103) for the mcu. I assume it also has an ST7920 variant, probably due to part sourcing/shortage issues, resulting in the bad display behavior.
I believe this is the same issue referenced here:
Ender 3 pro lcd Text lines jumbled - General Discussion - Klipper
Incorporating these two files would be helpful as I would like to stay current on the main Klipper branch rather than having to potentially merge every time I grab a newer release. These changes also shouldn’t result in any negative impact when running on a genuine ST7920.
Thank you!
