Visible Aliasing at 8K on RaspPi4 64 bits Caused by 16-bpp fbdev ?

I am running into a display issue with NanoDLP on a Raspberry Pi 4 running 64-bit Debian Bullseye. I am getting aliasing artefacts along the longer dimension of my 8K screen when using the vc4-fkms-v3d driver.
I suspect this is caused by the 16-bpp framebuffer format used on Raspberry Pi OS 64-bit.

I tried enabling vc4-kms-v3d, but I cannot get any output on my screen with this driver.
The screen is connected through an external 8K HDMI driver.

Is there any alternative way to display images on the screen using the modern KMS pipeline (vc4-kms-v3d) on Raspberry Pi?
