yes, I did. I can see that some of the visual changes you run there trigger repaints of all components on the screen. And this is happening several (too many) times for each button press. There is a manual away of resolving that by using Lua function to stop and resume the window repaint processing. That would definitely improve things, I am trying, however, as part of the work on the 3.7/4.0 make changes so that the (lua) preset developers do not need to do this manual control of the repaint process.
The most recent beta will be shared here tomorrow. I just need to finish description of the changes so that you know what has changed and how to use it.
