Not sure if such a heavy file is needed for this?

One thing I noticed is that you have to switch the Display Channels to Color to see it properly in the Image Editor.
(without doing this, I am getting transparent pixels where geometry is)
This I can reproduce with the default cube

@amshiv : is that what you are talking about?
If not, please try to explain what exactly you mean by no mist pass (and also the difference between 2.82 and 2.83)

If something is already resolved in a newer version [but not in 2.82], there is usually no backporting, we can only consider adding it to 2.82a

The image channel selector needs more to check the current pass type it is showing that I would categorize that as a bug. Solution is not that complicated only takes a lot of testing. I can look at it next week as it is annoying. But it has nothing to do with the mist pass, depth pass and other single value passes have the same issue.

Jeroen Bakker changed title from ~~Mist pass is not working on 2.82~~ to Switching between passes in the image editor can make the channel selector invalid.
