Sorry to say, Bullseye gets the same Intermittent Screen Blanks as Bookworm. Because they both get the same EDID error from the same :

[ 3.995639] vc4-drm soc:gpu: [drm] Cannot find any crtc or sizes
Before I tried Bullseye, I loaded the original Kanux 4.3.3 (stretch) which does NOT get the screen blanks. Because it does not use vc4-drm to get the EDID information. The only thing I could see in the dmesg that looked like Display code was:
vc-mem: phys_addr:0x00000000 mem_base=0x3ec00000 mem_size:0x40000000(1024 MiB)
vc-sm: Videocore shared memory driver
I ran the benchmark on (stretch) :
Graphics:
Device-1: bcm2708-fb driver: bcm2708_fb v: kernel bus-ID: N/A
Device-2: bcm2835-hdmi driver: N/A bus-ID: N/A
Display: x11 server: X.Org v: 1.19.2 driver: X: loaded: fbturbo gpu: bcm2708_fb
resolution: 1280x800
API: OpenGL Message: Unable to show GL data. glxinfo is missing.
(stretch) has very few OS commands available so I had to install Raspi-Config to show Resolutions and saw these 4 lines:
CEA mode 4 1280 x 720 16:9
CEA mode 16 1920 x 1080 16:9
DMT mode 4 640 x 480 4:3
DMT mode 28 1280 x 800 16:10
The last one, mode 28 was selected and it did appear that is what resolution (stretch) was using.
I would say that Bookworm needs some configuration help for my HDMI Controller Driver Board HC10MST_K with Graphics Chip TSUMU58CDT9-1. Maybe a patch for Config.txt.
