On an i9 Intel Imac with Radeon Vega when selecting the “Sharpen” tool and attempting to make the brush smaller, the cursor is updated every 2 seconds, stutters, the spinning wheel keeps on spinning (not the mac spinning wheel, but the one in the program that signals it’s “working on it”). When it stabilizes after a few minutes, it’s still unusable with refresh on the mouse movement of one second.
