I am trying out smoke simulation and I am having a problem about the smoke showing up in Cycles. EEVEE will render the smoke just fine, but when I try to render with Cycles nothing shows up. After trying out everything I could think of, I tried opening the scene in Blender 4.5.5 and there the smoke showed up as expected in Cycles with same default settings, except density being increased. Has something changed in Blender 5.0.1 the smoke does not show up with same settings or what am I missing? It feels weird so major bug would go unnoticed, but I could not find anything on the bug tracker or elsewhere online.

Here's the file of the very trivial scene demonstrating the issue: https://walop.kapsi.fi/temp/smoke.blend

...yea I can't get the smoke to work either, even in new scene with quicksmoke. Works fine on EEVEE, but Cycles... nothing, doesn't matter if rendering on CPU or GPU.

If it matters, blender 5.0.1, linux, rtx3090.

Probably a good time to make a bug ticket out of that.
