Focus peaking disappears when recording in RAW.

[carles.castillo]

Hi all,
I use ML in my 5Dmark III (1.2.3) and when film in 1920x1080 RAW the focus peaking disappears (not when I don´t film in RAW).
I can use it all the time, but when I press REC it disappears (only in 1920x1080 RAW).
Do you know why?
I always film underwater ant the focus peaking is very important for me.
Thanks,
Carles
