Wavelet Decompose takes too long due to expensive UI updates
Submitted by Alexandre Prokoudine
"I'm a pro photog. I live by wavelet decompose.
With layer grouping, 2 min 20 sec for a 7-layer decompose, and -45- seconds more to re-order the layers (!?).
46 seconds -total- if layer grouping is turned off.
18 seconds using 2.8."
Regarding 2.8, I'm sure he means the 3rd party plug-in by Marco Rossini (https://github.com/mrossini-ethz/gimp-wavelet-decompose).
