"screen-door" crosshatching on Ursa Mini 4.6k images
![Post Post](./styles/bmd_universal/imageset/icon_post_target.gif)
Ran into an issue looking at some enlargements of the image on a 4:1 compressed RAW shoot I did yesterday that show a regular cross-hatched pattern on the entire image. Does not appear to be FPN, it's something else.
Here's a dropbox link to the enlargement (jpg): https://www.dropbox.com/s/lfnit698z2ddkol/46k%20crosshatch%20enlargement.jpg?dl=0 (show it in full-screen on dropbox)
And a link to the full-size image (jpg): https://www.dropbox.com/s/lfnit698z2ddkol/46k%20crosshatch%20enlargement.jpg?dl=0
I can't seem to post multiple image attachments here, so this is a link to my post on BMC User.

And here's a dropbox link to the 4:1 compressed dng. If you zoom way in, you'll see it. It looks this way no matter what scaling option is used in Resolve (Smoother, Sharper, Bilinear). Is this an artifact of 4:1 compression on the UM4.6k or is it something else?

Note that I sent this off to a friend, he brought it into Resolve and (in Rec709 profile) saved it as a tiff and when viewing this at high magnification we don't see the crosshatching, just normal pixels. Here's a link to that:

Anyone have any idea what's going on here?
