Hello, when I use the MouseRangeManipulator to change the window width/window level in a touch screen device, after the sliding ends, the sliding again, the value is not continuously changed, the initial value will be reset. I don’t have this problem with a mouse on a pc. What is the reason for this?

Hi, I just tested this and can reproduce it. Can you post this as a bug on the vtk.js issue tracker on github? It’ll help us track the issue. I will be looking into all of the recent touch issues in the near term.
