    I don't know if it's related to my last post: https://www.telerik.com/forums/radopenfolderdialog-generate-a-lot-of-exception

    But that dialog is not usable if it's slow like that.  (see video compare to standard windows explorer, https://send.firefox.com/download/9e9308b253d19daf/#Xz4Pj9NHmh7NnG95iTlRRw)

     

    I have a GetForce RTX 2080, I have 4k monitors and I use Windows 1903.  And I use WPF UI 2019.3.1023.45

    Hello Mathieu,

    Thank you for the provided video.

    I tested the First Look example of the RadFileDialogs, however I was not able to replicate the same delay with the dragging operation on my end. 

    Are you able to observe the same behavior with the First Look example of the RadWindow? Can you replicate the same scenario in a standalone sample project? Additionally, can you share if you have increased the Windows DPI on your end? 

    I am looking forward to your reply.

    -I have the same problem with RadWindow
    -I have 200% scale in Display Settings, I still have the problem with 100% scaling
    -I have the same problem in my app, without the debugger it's the same behaviour as the demo.  With the debugger attached it's like 100x worst

    Hello Mathieu,

    Thank you for the update. For the moment, we are not sure what could cause the observed behavior, however we will continue trying to replicate it on our end. 

    May I ask you to update the demos application to the latest version and give it a try? Additionally, can you try modifying the Windows Mouse Settings to see, if any of them have influence over the dragging speed? Can you also share whether the monitors on your end are touch monitors? Can you try dragging around another application (Excel, Word) to compare the dragging behavior?

    I am looking forward to your reply.
