Problems with Adobe Lightroom Classic and Kamvas 13

Hello,

I recently purchased the Kamvas 13 and have been testing it with Adobe Photoshop and Lightroom Classic. I find that most things work ok, but for some reason in Lightroom Classic there is a lot of latency when trying to move the sliders in the Develop tab. It takes several clicks for the cursor to grab the slider and moving it is not accurate at all. In comparison, the sliders in Photoshop work perfectly. 

I have tried using the Pen button with pan/scroll function, but it works very poorly. It often jumps up and down when I simply click on the button. Sometimes it manages to grab the slider, but again the accuracy is very poor.

I am using Windows 10 Home version 20H2.
Lightroom Classic version 11.0.1.
Kamvas 13 firmware M19f_200904.
Driver version v15.5.1.390.
