I have gs 9.26, but with `preview-pdf-color-adjust-method' set

Doesn't a redisplay (typing C-l) make the expected image appear
there?
I sometimes get similar blank rectangles and they turn into
expected
images when I type C-l. (Though my gs is not 9.26, I expect it
doesn't
make difference.)
No, unfortunately it doesn't. I just checked the _region_.prv/
directory where the images should reside, and all there is is a
single preview.dsc file. When `preview-pdf-color-adjust-method` is
set to t, it contains a bunch of png files.
So it seems that for some reason the conversion from dsc to png
doesn't work. I included the output of `C-c C-p C-b` in both cases
below. The only difference seems to be the `-dDELAYBIND` argument
passed to `rungs`.
The preview.dsc file that's created in the bad case
(preview-pdf-color-adjust-method) seems far too small to contain
any useful information (I included it below as well), but because
the preview.dsc file seems to be deleted in a successful run, I
can't compare the two.
