Seriously, I have zebra working on my Ixus 95 when focus zoom is OFF, save as RAW works OK with CHDK RAW, but DNG RAW files have a shiny purple tint to them. CHDK histogram seems OK. On the negative side, the OSD font is far too small
[Edit] build 922, using CHDK-Shell, all compile options OFF.
Zebra also works with focus zoom ON.
Grids are shifted to the left of the LCD instead of being centred.
Tv override works.
