Drawing much slower than GIMP 2.8

Description
Brushes which have reasonable performance in 2.8.4 are rendered very slowly in git in any mode (8bpc to 32bpc).
With a spacing of 1px, fuzzy, rectangular brush, 25px in diameter, no dynamics, dragging out a line of 200 px length takes 3 to 4 seconds but happens instantaenously on 2.8.4.
Adding dynamics or using a bigger brush is out of the question. Waiting times with normal production-like settings go up to a minute for even the shortest lines.
