Hi,

This happens with VB 6.0.4, but also happened with 6.0 and 6.0.2. It also happened with the latest versions of 5.x.

When you drag the Mac VM window, inside which the Windows VM is running, the Mac window moves on the screen. However, its content is not moved, and remains in the same position.

To fix this issue, you have to minimize the Mac windows, and then put it back to the regular size. From here, everything works fine.

All VB Mac extensions, and the VB Win extensions are up-to-date.
As you can see in the image, on the left, a bit low, filled in black, you can see the Mac's window frame. On the right, higher in the screen, what is supposed to be its content (the Windows desktop).

Below, what I can see at that time in the Console.

Best,
Paolo

This is a known issue with macOS versions High Sierra and later. See #17168: VB display frame and content are no longer bound in High Sierra (osx 10.13) for details of the available workarounds.
