Grub background is found but not showing

Question

This is my grub.cfg:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""
# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos png"
# Uncomment to enable Hidden Menu, and optionally hide the timeout count
#GRUB_HIDDEN_TIMEOUT=5
#GRUB_HIDDEN_TIMEOUT_QUIET=true
# Uncomment to use basic console
GRUB_TERMINAL_INPUT=console
# Uncomment to disable graphical terminal
#GRUB_TERMINAL_OUTPUT=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1024X768
# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep
# Uncomment if you want GRUB to pass to the Linux kernel the old parameter
# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true
# Uncomment and set to the desired menu colors. Used by normal and wallpaper
# modes only. Entries specified as foreground/background.
GRUB_COLOR_NORMAL="light-blue/black"
GRUB_COLOR_HIGHLIGHT="black/white"
# Uncomment one of them for the gfx desired, a image background or a gfxtheme
GRUB_BACKGROUND="/home/joel/grub/115887-archboot.png"
#GRUB_THEME="/path/to/gfxtheme"
# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"
#GRUB_SAVEDEFAULT="true"
after, runing grub-mkconfig:
Generating grub.cfg ...
Found background: /home/joel/grub/115887-archboot.png
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
done
When I reboot, I can see the colors in menu, but not the image:
1.- Yes, the png exists
2.- image file is 1024X768, same as GRUB_GFXMODE
3.- I try commenting and uncommenting the lines GRUB_COLOR_HIGHLIGHT and GRUB_COLOR_NORMAL, and still not showing the background
any ideas, please?
