I’ve created a feature request. It would be nice if you can check whether this happens on your system with your own raws and histories. It would only take a few minutes.

I noticed that with the 5.0.0 appimage, DT is doing a lot of recalculation which… seems potentially unnecessary.
When you change something late in the pipe, it is prone to recalculating the whole pipe, whereas you might hope it would realise it's only from the point of change that the pipe needs recalculating.
To demonstrate -
Take an image with some chunky processing so the effect is clearly visible, e.g. DorS hard deblur. (Or do -d perf)
Add something late in the pipe like Local Contrast or Tone Curve with a raster mask that is an instance of say Exposure.
Now toggle Local Contrast off and on.
Notice that the offs are quick but the ons are slow because of pipe recalc.
Yet neither the raster mask, nor anything else, has changed prior to Local Contrast.
If you're using Tone Curve to make some final tweaks, it is quite frustrating!
Ubuntu 22.04, no GPU card
Yes, but only with raster mask. When switching to “normal” mask, everything is fine.
Seems like dt recalculates everything beginning from the source module of the raster mask, which is exposure in this case.
