Hi.
Our customers started to use high DPI 4K screens with a dual monitor setup. The left screen has a 4K resolution with scaling enabled and the right screen has a standard 1920x1080 resolution without scaling.
Whenever they undock a dockable pane and try to move it to the second (unscaled) screen, the placement starts to behave very erratic.
Our application is not DPI aware and we let DotNet handle the scaling. We were also able to reproduce the behavior with the TouchEnabledDockManager example, that comes with Infragistics. As soon as you drag a pane over to the second screen it's placed on a wrong position. And then it's impossible to move correctly. Sometimes it vanishes altogether. I recorded a video, since it's hard to describe the erratic behavior:

Note that I took this video on my developer machine, which does not have a 4K screen. But there is still the same effect if you change the scaling of one screen to above 100%.
Version of Infragistics and Windows:
Infragistics 17.1 20171.1008Windows 10 1703 15063.502
Hopefully you can help us solve that problem.
Regards,Norbert Harrer.
Hi Norbert,
Thank you for bringing this to our attention. I can see this happening in our samples using a simple two-monitor setup. I will write this up for developer review.
Please let me know if you have any questions.
I have investigated your issue and I have asked our engineering staff to examine it further. To ensure that it will receive attention, I have logged this behavior in our internal tracking system with a Development ID of 241117. This will be assigned to a developer in a future sprint to review my investigation and confirm my findings or to offer a fix or other resolution.
Thank you. Appreciate the effort and looking forward to your developers findings.
Sincerely,Norbert Harrer.
Just curious. Has there been any progress regarding this issue? Our customers keep demanding a fix for this problem.
Sincerely,Norbert Harrer
Hello Norbert,
Our developer finished reviewing the floating window preview outline is drawn in wrong location when dragging between monitors with different resolutions issue. Currently we do not support per monitor Dpi. After researching and testing this issue we realized adding support for this functionality is not feasible as a small development issue fix. This functionality has to be implemented as a planned feature.
