MacBook hardware cursor drop frame issue

Hello, when I was running World of Warcraft on m3max MacBook, I found that when the mouse appeared and disappeared, it triggered a serious frame drop (120 suddenly dropped to 70-80). Is there a way to fix this without closing the hardware cursor?(the cursor would be misaligned in full screen mode). Another issue is that when there are multiple input methods, the input method prompt box always pops up in the screen.

Thanks a lot
