Why do you have to do this manually? It would be much better UX if
Darktable could have a cache of the last N (configurable number)
rendered images, automatically.

Are you aware of the darktable-generate-cache command?

On my slow laptop with no discrete GPU, using arrows to move between
single photos on lighttable results in a brief flash if the thumbnail is
not cached, but one it has been cached the transition between photos is
very smooth.

Thanks Matthew, Chris and others,
I've dedicated more time to solving this.
"Snapshots" (or what I would call the "Compare" section where a
person can "Take snapshots") looks useful. I regret that it doesn't
suit the use-case where a person simply needs to go through the
photos in a slideshow-like fashion, to compare subtle differences
and determine what they'll do.
I tried the Slideshow feature.
The computer turned into a rocket system. I've never heard it work
so hard. I thought it might blow up (version 3.2.1 linux). All I did
was tap forward and back a couple times to test how Darktable would
handle the transitions. For 7 minutes my computer was not
responsive. For 3 minutes my mouse cursor was frozen. I was on the
verge of resetting the machine, but didn't because the noise it was
making was improving.
I tried searching for the 'Culling Mode' and found this resource
(https://discuss.pixls.us/t/help-with-culling-mode-in-darktable/12296 sorry
but searching the official documentation didn't work without
javascript). I discovered that a user can hold "W" or "TAB" to get a
fullscreen mode. Great!
Unfortunately, I still got flashes.
The reason for the flash is the photo is drawn in the top-left of
the lighttable panel and is then re-positioned to the center of the
screen. A bit disturbing.
The "Culling" mode gave me a similar flash. A tiny 10x10 pixel crop
of the image is drawn in the top-left of the lighttable before the
image is quickly re-drawn in the center of the screen.
My last attempt was to try the Lighttable's "File Manager" view. I
adjusted the slider alongside the "Mode chooser" so only 1 image is
shown at a time, rather than the usual 6. Now I can press the arrow
keys to move between photos. This also suffered from brief flashes.
See the "re-positioning" problem mentioned above.
If there are no objections can we please try to fix these flashing
problems in both the lighttable and darkroom (see previous email) asap.
To help the UI feel responsive while a photo is being added to the
cache, I suggested in the last email a change of mouse cursor and
short message in the bottom metadata bar.
Any objections to fixing these?
