Mode switch memory leak, switch gradually slower

Import both attached controller and script JSON file and install it into Live with Twister connected. It is a script with mode switch. To switch between 5 available modes, press the knob-button 1, 2, 13, 14, 15. (Counting from top left to bottom right)

At file's start up, the switch is instantaneous. However try mashing 5 knob-buttons for about 1-3 sec, you will see mode change could not catch up and "dequeueing" change slowly that you could see it catch up. This is not a problem, however, from that point on you will see that mode change is noticably very slow compared to when you just opened the file.

To restore the same mode change speed, reloading the project file or new project will reset mode switch speed to fast again. The slow down only affects CSS mode change, the knob controlling parameters are still instant.
