Recently after I installed macOS Catalina and reinstalled Minecraft, whenever I left click in minecraft, I get huge frame drops. Normal clicking drops my fps by about 30, and butterfly clicking drops my fps by about 80fps. It also makes my mouse movement very unpredictable. This only happens when I left click, only in Minecraft. I've tested it. I'm not sure what's causing this, I've tested it on a clean 1.8.9, no mods whatsoever, but it still happens. Well, in clean 1.8.9, the frames don't drop as much even when I butterfly click. It drops only about 20fps.
