Corrupted preview in darkroom

[kofa73]

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

While editing in the darkroom:

• while moving around, or while the editor preview was recomputed for some other reason, a colourful 'storm' of pixels appeared. These later disappeared, as the computation finished
• the navigation view (top left) preserved some of that:
  

I'm attaching the console log.
darktable_-d_pipe_-d_cache_-d_common_-d_opencl_-d_perf.txt

Steps to reproduce

I'm not sure what module caused this, and the corruption only appeared after editing the same image for over an hour, in different versions.

The raw file is DSC_0856.NEF from: https://discuss.pixls.us/t/filmic-when-to-use/13250
The sidecar:
DSC_0856_02.NEF.xmp.txt
The history was at a different step than in this XMP, as I quickly grabbed a screenshot and then tried messing around with modules to trigger it again.
