Result of 100 px feather in 3.0

Description Spencer Brown 2016-06-06 17:05:14 UTC 
Feather selection blurs the current selection. Its keyboard shortcut is Shift+F6.

In 2.9 if you put in a radius of 100 you would get a nice, smooth, long blurred transition. In 3.0 even if you put in a large number you only get a small amount of feathering.

Reproducible: Always

Steps to Reproduce:
1. Make a selection.
2. Press Shift+F6 to feather it. Put a large number in the parameter field.
3. Paint across the border and note the small transition area.

Actual Results:  
The transition is much smaller than the number I put in.

Expected Results:  
The transition should be the same size as the number I put in.

I'm using the 3.0 release appimage on Ubuntu 16.04.

In the meantime I'm using a big soft eraser brush to get the large transitions that I need for my work.
