Hi,

 

a found a rendering issue i assume a bug.

To see the issue, please uncheck the 3 top layers in the stack, and then toggle layer 3 (merged after de-bayer)

  • In the lower area, the merge shows relevant differences (the layer 2 "mark area" can be activated to frame the impacted region).
  • The issue occurs while export, too (with top 3 layers de-activated).
  • Layer 1 is a PNG file showing the result of export (with "merge visible" in-active while export).

If you are asking what this composition trys to achive:

  • use a test picture (from wikimedia)
  • apply a PT filter to convert pixels into R/G/G/B bayer filter
  • merged the result and put it into a new file as bottom layer
  • used perspective live filter to downsample R/G/G/B pattern into a new region with 1/2 resolution. I did not find a better way, tried pixelate (destructive), custom blur (bad results)
  • when using different zoom levels at that stage (everything above de-bayer downsample deactivated), Photo gives horrible artefacts. So i tried to merge visible, but this results in a 56 pixel high area on bottom.

I use iPad screenshots and videos even in the Desktop section of the forum when I expect no relevant difference.

On iPad, merge visible does not show this issue.
