I have something they weird with a few app (e.g mail, message...)

E.g in Message, when I have my cursor on the top of a conversation and I scroll to the left to delete the conversation, the UI stop responding (but the process is still working fine)

I removed com.apple.driver.AppleBluetoothMultitouch.mouse.plist but didn't help

  • What kind of mouse do you have? I had a brand new Logitech BT mouse and it suffered lag just like that.

You are not first how met this problem.

From above support request no one doesn't know any workaround for resolving this rude bug. Hope it will be fixed at the nearest updates.


I take it back in my case removing this plist solved the issue
