Hi, I have an HMI screen built in perspective which has 10 gauges on it with expanding panels to reveal powercharts - these are dynamically loaded and removed from the view when not in use. I have found though, if the screen is left on for a few hours - if you go to tap the buttons there can be a noticeable delay. This goes away if the screen is refreshed.

Has anybody noticed anything similar? Or any tips to ensure the screen is as performant as possible?
