I'll explain my setup and maybe that'll help. My MacBook display is set at 1710 x 1107, but I think in pixel terms I think it's double that, so 3420 x 2214. In my other software, Touchdesigner, I tell it to output a colored square in the bottom right corner at the size 200 x 200. You'll see that in this screenshot:

Now for HyperHDR, it sees the square as double the size (actual pixel size) as 400 x 400, because it also see my MacBook display as 3240 x 2214. So I need to subtract 400 from both (so it can center in on the square), so I set the crop to 3020 x 1814. And that works perfectly. See here:

But now whenever I restart HyperHDR I get that Rejecting invalid width/height values as it collides with image cropping: no matter what "Max. Stream Width" I set it too (I've tried smaller than 200 and I've tried 400 and above too). It only fixes itself when I set the crop values to 0 and save, and then put them back at 3020 x 1814 and save again.

In this situation, how can I fix this?

@awawa-dev have any insight on this? am I doing something wrong? I have a pretty easy workaround on my end (deleting the crop values and then putting them back) so no worries if this isn't worth the time to fix (or if im actually doing something incorrectly)

Currently Im completely out of resources. No sure when but I will look into it.
