Hyperpixel 4.0 Square (No Touch) Screen Scrolling / Ghosting #205

Upon Installing the legacy drivers (option '1' for 'weirdly square' 'no-touch' and rebooting. Display shows boot splash screen just fine, but at the desktop the image "scrolls" like a only CRT monitor, and the display is "ghosted" showing artifacts.

Product Purchased: HyperPixel 4.0 Square - Hi-Res Display for Raspberry Pi - Non-Touch - PIM475 Purchase Date: Sept 2023 Connection Type: GPIO with extender

My Pi: Raspberry Pi 4-B OS: Debain Version: 11 (Bullseye), kernal version 6.1

See here for YouTube video showing the issue.

Anyone have any solutions for this? I am assuming this is not a hardware issue, as the splash screen displays just fine.

Currently installing a fresh image of Buster and starting from scratch...

Fresh image of BUSTER and reinstall of the hyperpixel '-legacy' curl using options [1} (Pi 4 Weirdly sqaure] and [0] (manufactured after 2021) solved the issue.
