ROI manager painfully slow (macOS)

Does anyone else experience this? I hadn’t needed it much before, but now that I need to use the ROI manager, I realize how excruciatingly slow it is. Operations I’m doing are the most basic ones, such as drawing ROIs and saving them, moving them around, updating them, transferring them from one open image to another. My images are also only 500x500. What gives? Everything else generally seems to be okay-fast-ish.

Maybe related to this:


Thank you! That fixed all speed issues.
