I still have a huge latency problem with touch screens. I have two different computers with two different touch screens.
Same effect on both. One second latency on buttons in show mode, or any mode for that matter.
And a 4 to 5 second latency to switch bettween modes or pages.
really anoying when you need to react on cue with the music.
Could you look into it ?
BTW, if I disconnect the USB port of the screen and use a mouse, the latency desapears...
