Deferred rendering for chained subpasses

Hi,

I am trying to trigger deferred rendering for 2 * N subpasses with each couple of subpasses taking the same 2D images of depth and color as input and outputing a new color in a common result image.

  

It works for a single couple as you can see below:

I am still wondering what it loads from GMEM, but at least it seems to merge the subpass 0 with the subpass 1 (Surface 185 is ImGUI).

But for 2 or more couples:

all the subpasses are split. Is it simply not possible or could someone point me to potential issues in this setup that could prevent the driver to merge all subpasses?

Thank you in advance for any help, do not hesitate to tell me if I do not provide enough details.

Best regards,

Sebastien Gachoud

For some reason, the image containing the diagram of the subpasses does not show up in the post, any hint why?
