All my Macs have Retina displays, but the MacBook is a 13” and has a comparable
resolution to the Surface. Nevertheless, Darktable is much more usable on
Windows than on the (faster) MacBook.

All the SSL certificates under *.darktable.org seem to have expired yesterday,
and whoever is managing the LetsEncrypt setup probably forgot to turn on
auto-renew :)

CPU load does increase a fair bit when I move the mouse. Not up to 100%, but
rather too much for comfort. Reading through the issue description does make it
seem like the entire lighttable is being redrawn on every mouse move, which is…
sobering. From the descriptions there doesn’t seem to be enough event filtering
to figure out if the redraws are warranted.

Well, that kind of negates the point of having a lighttable… One of the reasons
I switched to Darktable is the library management features, and the (relative)
ease for triaging shots…
Thanks for the enlightening reply,
