Win10 x64, nVidia GTX 780 3GB
Broken: Official 2.79, Buildbot builds, own build
Short description of error
Large resolutions (in my case 5000x5000 which is not insane but more than 1080p) in combination with the Denoiser cause the memory to increase during rendering, sometimes up to the point where my GPU RAM gets filled up completely. Same happens on CPU but I have enough system RAM to at least finish rendering.
This even happens with a completely empty scene (no geometry, no textures).
Without Denoiser both GPU and CPU render rock solid without increasing memory.
Exact steps for others to reproduce the error
- Open this scene
and press F12 to render (or just open Blender, set resolution to something like 5000x5000 or above, activate the Denoiser and then press F12.)
- Watch memory increase
- Same goes for CPU
- Deactivate Denoiser -> the empty scene renders with less than 20MB memory used.
