I've noticed that dragging a floating dock panel over to a second monitor leaves artifacts on the screen; the glow edges around the form are displayed dislocated from the form. The issue is easily reproducable with the docking pack demo from your website. Please see the screenshot attached.
The issue occurs when the second monitor uses a different DPI setting (scaling factor) than the primary monitor. I'm using a scale factor of 125% on my laptop, for example, but when I attach an external monitor, Windows 10 sets the scaling to 100% for this monitor. Undocking a dock panel and dragging it over to the second monitor shows the issue outlined above.
Is this a known problem?
