Interfacing (DSI, CSI, I2C, etc.) • Screen duplication artifacts with DSI interface

Hello, This is a continuation of this thread (viewtopic.php?p=2207258#p2207258) on the ICN6211, but I think this is more of a DSI configuration or Panel Timing issue so I'm breaking it off to another thread.

I'm getting some odd artifacts on my screen, I'm not sure if these are due to bad panel timings front/back porch or sync or if its to do with the DSI config.

The screen is working as shown below, the desktop environment shows up fine:

But depending on the context of the screen (like opening up the home menu) the screen bugs out and shows duplicates/artifacts:

Any ideas on the issue? I've tried to adjust panel timings without much success. My dtoverlay is:

Code:

dtoverlay=vc4-kms-dsi-generic,one-lane,clock-frequency=24284160,hactive=800,hfp=8,hsync=4,hbp=8,vfp=8,vsync=4,vbp=8
