GIMP is running slow on Big Sur

Subsequently to updating to mac os Big Sur, I opened Gimp and noticed straight away that all the drawing tools were jerking around. You could move the mouse to a spot and it would take about a second for the tool to jump to it. While this in and of itself renders the program unusable, I still tried messing around with color grading some photos and noticed that basically the entire program is running slower as a result of the update.
