What I have noticed while working with canvas size 16,000 x 11,000...some operations take an especially long time to conclude, making Gimp appear "locked", although it'd actually chuffing away.
For example, a bucket fill operation, even within a relatively small target area of the larger picture, for instance only 150x 200 pixels, can take 45 seconds to actually paint the target. My guess is that's because Gimp has to calculate it''s task relative to pixel 1;1 of the graphic, so there is a lot of heavy lifting going on under the covers, despite the appearance of a simple task. Paths on really large canvasses take a long time to process, as well.
In fact, I've been getting a surprising amount of outright crashes when stroking a path on large canvases, more so than I've ever experienced with Gimp before, which is heart breaking when I've got considerable work in progress that just goes "poof" along with it.
What I've done is to modify my workfow, performing all the other "non-path" tasks as a group, then saving that as an interim work, before embarking on any extensive path work.... saving paths for last....which the strategy has eliminated a lot of frustration.
I've been knitting "tiles" together of an old map that I found in a multi page format PDF online source. Importing into Gimp at 600 PPI, and then touching up the join areas. And it was going so well I decided to expand my work, ultimately enlarging the canvas to 16,000 x 14,000....whereafter Gimp got REALLY crash prone...crashed like half a dozen times just this afternoon. But having learned the hard way what to expect, I just saved a copy before plotting any path, just to be on the safe side.
Probably need to buy a new laptop, my current machine is maxxed at 8 GB ram..
