I have developed a Point-of-Sale solution with WPF using .NET Framework 4.8 running on a touch resistive screen. I am getting complaints from customer that the application doesn't always respond to touch, when for example a button is pressed, or tab item is clicked, and the customer will have to click a couple of times on the control for something to happen. I read somewhere that there was some bug with touch support for WPF but that was for .NET Framework 4.6. Any thoughts?

Hi,@JohnMartel .Could you share the relevant documentation you've read? Is it possible to show the zip link of the project to analyze the project code? What is the user's device model? Is the system environment Windows or MacOS? Is it an individual device problem?
Hard to say without seeing code. Is it possible the button size is too small to touch easily on your customers pos?
