GRUB's PNG reader (grub2 bookworm) fails to load bee-logo.png despite the file being valid RGB 8-bit non-interlaced PNG with minimal chunks. Root cause is a known fragility in GRUB's png.c; exact trigger is unknown. Switch to uncompressed 24-bit TGA which bypasses the PNG parser entirely. tga.mod is already present in the ISO (x86_64-efi/tga.mod). - Convert bee-logo.png → bee-logo.tga (480018 bytes, BGR top-left) - config.cfg: insmod png → insmod tga - theme.txt: bee-logo.png → bee-logo.tga - Document all prior failed attempts in git-bible/grub-bitmap-error.md Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
