Posted 3 months ago by Tvema
Version: 19.1.0684
Platform: .NET 4.7
Environment: Windows 10 (64-bit)

Steps to reproduce:

  1. Have DockSite.UseDragFloatPreviews="True" on a touch screen enabled device
  2. Tap and hold on a docking tab or window header until Windows 10 touch gesture rectangle appears
  3. Try moving finger as if you're undocking a window/tab
  4. Semitransparent blue rectangle appears and blocks interaction until the app is reopened

Reproducible on Simple IDE demo from Sample Browser (need to check menu item at "Options" > "Use Drag Float Previews").

Below is a screen recording uploaded on Google Drive which shows how to reproduce the bug.
