Preview and/or Int Slider setting Bug

What happens on my computer with this filter:

0) There are issues with how the previews render. They don't match the Int Slider settings. The previews seem to (occasionally, not always) draw with a different slider setting than the actual image. This may be related to the Int Slider problems with Groups.

1) When I switch from this filter to another filter and back, even the main image now renders with a different Int Slider setting. The actual setting doesn't change, but the wrong value is used by the renderer. Specifically here, the Int Slider has been remapped so the step is 2. This seems to be ignored by the Group (or by the renderer) and it is rendered as if there was no remapping, passing the value 2 instead of 4.

It happens to Slider control as well.
This bug seems be a control remapping bug.

Thanks for reporting! This looks like a preview cache issue rather than a remapper bug. A bug point for ThreeDee.
