Floating dock panels on multi-monitor system (Windows 10)

Alaska Software Inc., Germany

Hello all,

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?

Need some time to check.

Hi Eugene,

Is there any new information available on this issue? I have tested it with your new demo (January 15, 2019). See the screenshot attached. I have started the demo on 96 PPI, then moved 'Panel 3' to 192 PPI (200% zoom on 4k monitor). As you can see, 'Panel 3' is not scaled (it still has the scaling parameters of the original monitor), the gloowing edges seems to have the correct size, but are wrong positioned (or the panel is wrong positioned). The good news is that the form itself scales like it should :-)

Thanks in advance!

Hi Eugene,

I have been testing this with the my own project and this seems to be fixed. However, I encounter two new problems with floating dock panels on a multi-monitor setup, see http://forum.lmd.de/discussion/829/floating-dockpanel-doesn-t-resize-correct-multi-monitor-dpi-and-cannot-maximize#latest
