[Qemu-devel] gtk UI doesn't correctly byte swap 32-bit framebuffer on qemu-system-ppc little-endian host

[Mark Cave-Ayland]

Hi all,

I've just been testing some more OpenBIOS images with the new gtk UI and 
found that if you specify a 32-bit depth framebuffer on qemu-system-ppc 
running on a little-endian host then the RGB -> BGR byteswap doesn't 
take place.

Good:
./qemu-system-ppc -g 1024x768x32 -vnc :1
./qemu-system-ppc -g 1024x768x32 -sdl

Bad:
./qemu-system-ppc -g 1024x768x32

I've quickly confirmed this with git bisect which simply returns:

    gtk: make default UI (v5)


Many thanks,

Mark.
