What should have happened was when I press control + click it should send the same packet as a two-finger click.

What actually happened was the keystroke "LCTRL+Click" doesn't get recognized by the client, making the only option for control+clicking reseting your trackpad's features to make "button 2" a two-finger click or a click on the corner of your trackpad, etc.

This seems to be a simple bug with a simple fix, but it makes gameplay very challenging on trackpads.
