Description

System Information
Operating system: Linux-5.13.0-7620-generic-x86_64-with-glibc2.33 64 Bits
Graphics card: Radeon RX Vega (VEGA10, DRM 3.41.0, 5.13.0-7620-generic, LLVM 12.0.0) AMD 4.6 (Core Profile) Mesa 21.2.2

Blender Version
Broken:

  • version: 3.0.0 Beta, branch: master, commit date: 2021-11-24 09:05, hash: rB785503a7e4d1
  • version 3.1.0 Alpha

Worked:

  • version: 2.93.6 official release.

Short description of error
When rendering an image with a resolution of 20000x10000 makes the intermediate result fully back. The transparency checkerboard also doesn't show in this case. After rendering the image is correct.

Exact steps for others to reproduce the error

  • Start Blender
  • Set render engine to cycles
  • Set render resolution to 20000x10000
  • Disable denoising (has nothing to do with the error, except that it would be very time consuming.)
  • Press F12

I was able to render with 16000x8000

Can confirm. Black shows as long as either X or Y resolution are greater than 16384 (which is 2^14).
When I switch to Eevee I get an error about texture size limit, might be related?

This issue indeed roots into the same limitation as @Garek (Garek) pointed out: OpenGL has a limit on the texture size and in Cycles for 3.0 we are allocating one single texture for the final result. Technically it is a regression compared to 2.93, but not sure whether there is a way around it.

Guess the proper solution is to allocate multiple texture in the BlenderDisplayDriver when the render result does not fit into limitations of the OpenGL.

Marking as high priority to allow classify whether it is something we aim to be resolved before 3.0.

Best to keep the texture to 8Kx8K. The reported max resolution of the gl driver doesn't mean that allocation of smaller textures always work.

Maybe we could allocate one texture per tile, and limit the max tile size to 8k?

Good to know.

And to clarify: this but is something what is very nice to be fixed soon, but we do not consider this a stopper for 3.0.

@Brecht Van Lommel (brecht), That is definitely a possibility, and it does sound like it is simplest/cleanest approach. I'd need to think a bit about what exactly that'd mean for the display driver and graphics interop API.
