	Hello,

	gamma settings haven't change between 1.0.21 and 1.0.22. So I don't see 
where the color tint change you may come from. If you have the opportunity, 
running a preview with scanimage and SANE 1.0.21:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
scanimage -d genesys --mode Color --resolution 100 2>scan-1.0.21.log 
>scan-1.0.21.pnm

then with SANE 1.0.22:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
scanimage -d genesys --mode Color --resolution 100 2>scan-1.0.22.log 
>scan-1.0.22.pnm

	If you could send me these files (compressed), I'll have the opportunity 
to figure out what is going on.

Regards,
	Stef
