GNOME Bugzilla – Bug 794301
Spacing Brush Performance on GIMP 2.9+
Last modified: 2018-04-04 00:26:05 UTC
To increase the quality of brushes with natural effects, is necessary to work with small spacing values, ideally between 1~5. I have made a test series to determine which are the ideal widths to have a brushstroke without or almost the overlapping effect... circa 128 px width is a good compromise to many soft flat brushes. But, this is a specific case and would be a big thing to grown the performance in general of the small spacing values.
I think that this issue is already discussed in bug 694917 and, mainly relating the size and spacing brush issues. *** This bug has been marked as a duplicate of bug 694917 ***
