this is the upstream fix for the regression (since December) where Megapixels is taking pictures with a greenish or cyanish (depending on lighting conditions) tint. It has made it into 6.3 (see the above links), but not 6.2 nor 6.1, neither upstream nor in the megi kernel. It would be great not to have to wait months longer for the regression fix. (It has already taken 3 months.)
