I am seeing some terrible input lag on all versions of rebelle. I originally had 2 but hadn't used it for a while. Got a new tablet (x-pen 15.6) and thought I would try it out. Saw the lag with mouse and pen. Tried it in version 3 (3.1.5) and get the same result. Running on windows 10 with Nvidia graphics.
Tried uninstalling all versions and reinstalling with no joy. Not seeing anything like this with other packages.
Am I missing something?
