    It might just be me, and my set up, but I have NEVER found the hotpixel removal thing to work at all, in any circumstances.

    Well, Martin, it might not just be you, but you and me, at least among those that admit to it.

    Can anyone explain this phenomenon?

    There is an observation by others and me some time ago that the noise reduction tool only works in high zoom levels and is disengaged on lower zoom levels. Assumption is that this is for performance reasons.This can lead to what you've observed, as well as to magenta color cast for high-noise images.

    Distracting for viewing and image editing but in the end the export should not show any issues.

    DXO for example only engages sharpening the image preview in 70% or higher zoom levels or so (at least what I've observed), that is even worse.

    I believe I made a feature request years ago, not sure though, to set the zoom level optionally in the preferences, but I think there is little chance...

    Thanks, BeO. I'll try exporting.

    Exported 2 variants: one with zero single pixel value and one with a single pixel value of 10.

    The variant at zero showed the hot pixels still present upon zooming in on the jpeg, but the variant exported with a single pixel noise reduction setting of 10 did not show any hot pixels.

    The value of 10 was an automatic selected value by Capture One.

    So, no Lumix mystery :-)
