Hi,
Yes, I remember this option in the pref pane, unfortunately whatever it
is checked or not the problem remains... To be sure I quit DT and
reloaded the files (to avoid the possible presence of a cached file) but
there was no improvement.
This is indeed annoying since in my workflow I like to use the Z key in
the lightable from the thumbnails to quickly check if the picture is ok
or not. Now I'm compelled to copy the jpeg files too from the camera and
check their quality instead, as a temporary solution...

Regarding this particular issue :
(2) All DNG pictures appear strongly pixellized (with ctrl-Z
in the lightable) contrary to my CR2 or RAF files
That only shows low-quality thumbnail, so it is kind-of expected.
In the lightable, using Z or ctrl-Z of JPEG files straight from
the camera is ok; on the corresponding DNG files it pixellizes.
But meanwhile, if I work on the DNG file (even a little, for
example by putting a bit more exposure in the darkroom), and then
come back to the lightable, then Z or ctrl-Z magnifies the
thumbnail correctly...
I'm sorry to insist, but don't you think it's a bug regarding the
way DT handles Leica DNG files ? Why these Leica DNG thumbnails
would be expected (initially at least) to be of low quality and
not the others (from Canon or Fuji) ?

I suspect "don't use embedded preview JPEG but half-size raw" is disabled?
The thumbnail embedded in leica raw's, as you can see, is really tiny.
You could enable that option, and then you will never see the embedded
thumbnail.
