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?
