Short description of error
when the zooming in on the image editor removes meta data from the bottom left corner of the image. No meta data burnt into the image even if saving before zooming (while it's still on screen).

If the image editor is toggled to full screen before rendering then the meta data doesnt dissapear when zooming and the meta data is saved to the jpg when saving from the image editors save image option.

after render:

after zoom:

settings to get the meta data onto the image:

@3di Can you check if this happens when you load factory settings to exclude influence of addons and app handlers that may modify data after rendering?

ah actually, i'm using turbo tools, which replaces the render layer node with the cached render which was saved out to multilayer exr via output file in the post render handler. So I guess the file output node discards the meta data........but why does it get saved into the exr when in full screen...hmm.

close down if you want 👍

Thanks for info. Does that mean, that without addon this issue doesn't happen then?

If so, it would be best if you report this to addon developers, so they can check their code and eventually report the issue to us with reproducible example. It could be bug on either side, but I can't really tell from this report.

I'm the dev, but the code functions identically in full screen as it does when not, so if it were addon related, it should fail to keep the meta data in both instances.

I think the odd thing is that it's working in full screen, because I wouldn't expect the file output node to be able to store the meta data (only the composite node should store it to the best of my knowledge). So why the file output node stores the meta data in full screen is a mystery.

Close it down for now though. I'll go through it with a fine tooth comb to make absolutely sure it's not something in my code.

Just found the cause. If you refresh any image datablock, even though the image editor is showing the render result, the meta data gets removed for some reason. In full screen I guess for some reason the meta data doesn't get lost when an image data block is refreshed/reloaded etc.

I guess the report should be left open and retitled as 'refreshing image datablocks destroys meta data in render output'?

it's not a massive problem to be honest if you want to close it down. It still gets saved out during animation, it's just annoying if the user has rendered a still image and then wants to manually save the image from the image editor with the meta data. I imagine it would be a quick fix to not discard it from the image editor when updating non related image blocks though....I'll leave it with you 👍

Not sure if that is the root cause, Can't reproduce issue here at least.

try zooming in on the image editor after refreshing.
