This issue is most likely a duplicate of #83300 which is now fixed in newer daily builds. No word on if it will make it back to the 2.91 series yet.

I can reproduce this both in 2.91.0 and 2.92.0. The issue was introduced somewhere between 02677ec4e0 (2020-11-06) and 0f45cab862 (2020-11-25). It takes a while and apparently renders the first sample multiple times but at some point continues with the following samples.

I'm setting this to confirmed. I couldn't find a duplicate report for this, but it may have been reported before. Not sure if this is related but you can create a permanent loop / freeze of viewport samples by doing the following:

Start Blender.
Use Object > Quick Effects > Smoke on the Cube.
Set the render engine to Cycles and the device to GPU.
In the modifiers panel, hide the fluid in the viewport.

Set the viewport shading to Rendered.

This also worked properly in the build from 2020-11-06 02677ec4e0

This seems to be working fine in master now.
