I tried the following:
colin@localhost ~]$ darktable -d cache --library
~/.config/darktable/library.db
[image_cache] has 131072 entries
[mipmap_cache_init] using low quality compression
[mipmap_cache_init] cache has 8 entries for temporary compression
buffers ( 125.00 MB).
[mipmap_cache_init] cache has 128 entries for mip 3 ( 250.00 MB).
[mipmap_cache_init] cache has 512 entries for mip 2 ( 250.02 MB).
[mipmap_cache_init] cache has 2048 entries for mip 1 ( 250.06 MB).
[mipmap_cache_init] cache has 32768 entries for mip 0 ( 1009.00 MB).
[mipmap_cache] cache is empty, file
`/home/colin/.cache/darktable/mipmaps-cacd60b8ba500f50d692666b8427ba66b50f1728'
doesn't exist
[mipmap_cache] level [i0] ( 256x 250) fill 0.00/908.10 MB (0.00% in 0/32768
buffers)
[mipmap_cache] level [i1] ( 512x 500) fill 0.00/225.06 MB (0.00% in 0/2048
buffers)
[mipmap_cache] level [i2] (1024x1000) fill 1.46/225.01 MB (0.65% in 3/512
buffers)
[mipmap_cache] level [i3] (2048x2000) fill 0.00/225.00 MB (0.00% in 0/128
buffers)
[mipmap_cache] level [f4] fill 0/4 slots (0.00% in 0/8 buffers)
[mipmap_cache] level [f5] fill 3/4 slots (75.00% in 3/8 buffers)
[mipmap_cache] scratch fill 46.88/56.25 MB (83.33% in 3/8 buffers)
[mipmap_cache] level | near match | miss | stand-in | fetches | total rq
[mipmap_cache] i0 | -nan% | -nan% | -nan% | 0.00% | 0.00%
[mipmap_cache] i1 | -nan% | -nan% | -nan% | 0.00% | 0.00%
[mipmap_cache] i2 | 100.00% | 100.00% | -nan% | 50.00% | 100.00%
etc.
So I have sucessfully removed the cache, but it's not helping.
