Dear all,
First things first:
Fedora 32, Intel I5, 32GB RAM, Nvidia GeForce GTX 970.
Currently DT 3.4., but same problem occurred under 3.2.1 as well.
I searched this list to find a thread where a similar problem was found
under Win10, without a real solution. Besides I doubt that Win10 and
Linux are comparable in this (and other) respect.
When trying to re-edit a previously edited photo DT almost stalls. No
matter what I do, zoom in or out, retouch, move sliders it almost stalls.
Retouching a single spot using the healing tool takes about 2-5 minutes,
while one of the CPU-kernels is at 100% load, the other CPU-kernels are
not equally stressed. Yes I have CL enabled and running.
Meanwhile I can run any other apps without any noticeable slowdown.
I found out that compressing the history stack "improves" things to like
3-5seconds for retouching a single spot.
Editing new, that is photos that have not been previously edited, runs
smoothly.
Any ideas?
And above all: Merry Christmas and stay healthy!!!!
Henning
