GNOME Bugzilla – Bug 742270
FG Select tool too slow for real-life work

1. Go to http://www.flickr.com/photos/patdavid/9462268488/ 2. Download original image (3704×2456px), open in GIMP. 3. Activate Foreground Select tool with Matting Levin 4. Draw ROI selection around the woman's head. 5. Click 'Preview Mask' 6. Watch GIMP become unresponsive, eat all memory it can find and cringe to death, making the desktop (GNOME) barely accessible. I can sit down and what 10 minutes or more and not get anywhere. 'top' says GIMP 2.9's process east 1,2 to ca. 4,2 %CPU, and ~32 to ~58 %MEM. It's somewhat better with the Matting Global which even produces a usable result on this very same image, although it too becomes unresponsive for a while, with spikes of up to 99,7 %CPU and at least 21,1%MEM. In both cases (Global and Levin) the on-canvas progress indicator isn't accessible: clicking on the header does nothing. In fact, the mouse cursor doesn't even change from the currently selected tool's one when hovering it on the title.
Yes and yes, it's a huge PITA. The same is true for all sorts of GEGL operations that are shiny new replacements for old stuff that actually performed. Dumped into git and forgotten. I'll rather disable all that stuff for 2.10 than ship these "features". To save these ops into 2.10, somebody needs to have a close look, preferrably the original authors.
