Original GitHub issue: https://github.com/debauchee/barrier/issues/276

Operating Systems

Server: Windows 10

Client: MacOS 10.13.6

VirtualBox: 6.0

Barrier Version

2.1.0

Steps to reproduce bug

I'm running VirtualBox on the Windows server in seamless mode with a Linux guest. It appears there is an interaction with VirtualBox in this mode and Barrier where edge detection doesn't work (mouse does not move to client).

I found that in Scaled mode this issue is not present, digging further I did also find that turning on the setting "Don't take foreground window on Windows servers" and this seems to fix this issue. Not precisely clear what that setting means, but it seems to work.

The only issue that remains is that if a Seamless Virtualbox window had focus before going to the barrier client, the keyboard focus remains on the VM window while the mouse has moved to the guest. Clicking in the client doesn't change focus, first have to click to a native windows app before going to remote.

Other info

This is not a showstopper. It does work, clicking away from vm on server is a workaround. I'm just wondering if anyone else has experienced this, perhaps that setting helps others in this situation and if you can think of any fixes for that last issue.

Looking back in history I see others have reported similar issues in the older upstream versions.

Oh, and thanks for letting me remap Meta/Ctrl for the MacOS since most of the common keys are opposite windows interaction. Three different OS nuances is enough to contend with. :)
