System Information
Operating system: Windows 10
Graphics card: Nvidia Quadro 4000 (y2010)

Blender Version
Broken: (2.91, 2.92)
Worked: (2.83, 2.90 (different issue))

Short description of error
With viewport render disabled for a simple fire simulation, cycles repeatedly renders the first sample over and over again in the viewport render mode.

Exact steps for others to reproduce the error

Open Blender (2.91 or 2.92)
Create a simple Mantaflow fire simulation with at least one input and one domain.
Give the domain a simple volumetric material for the fire.
Set the render engine to Cycles.
Disable viewport rendering for the fire domain.
Click on viewport rendered view.
Watch Cycles try to repeatedly render the first sample over and over.
If you enable viewport denoising and set the denoise to start at one sample, the problem goes away, but is verrrry slow.

Try stopping the animation timeline from playing and the problem should be fixed.
