If you have a VST Applied to one Mixer and then decide to duplicate that same VST to another Mixer, your cursor goes invisible until you release the mouse left click button
1: Open the Mixer Panel on the bottom menu 2: If there is a VST in one of the Mixer, Ctrl + Drag the VST to another Mixer
The cursor should not be going invisible when Ctrl + Dragging (duplicating) the same VST to another Mixer
Apparently, when Ctrl + Dragging a VST to another Mixer, the program start to run in 20 FPS until you release the Left Mouse Button.
