YUV444 support isn't officially supported by the hardware, but
worked if you told it the image was YUV422 with double the width
and altered chroma scaling.
Adding BCM2712 support gained a fetcher memory (UPM). The code
handling UPM allocations didn't have a case for YUV444, so only
allocated based on the base width, and therefore underflowed.
Increase the UPM allocation size for the luma plane of YUV444
to match.

Linux kernel
There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
