Original GitHub issue: https://github.com/debauchee/barrier/issues/1987

What happened?

So firstly, great tool. Love it! Mostly works with minimal setup; far cheaper than a KVM.

I've recently encountered an edge case, where the native OS, hands off the cursor to an app, but it's not respected by barrier (because how would it be I guess?)

Every time I move my mouse, the barrier mouse appears outside of the captured window, as well as within it.
Because of the behaviour with screen edges; the mouse disconnects from the guest.

Software tested as affected:

Virtualbox (without guest additions)
DOSBox

Version

v2.0.0-RC1

Git commit hash (if applicable)

No response

If applicable, where did you install Barrier from?

GitHub releases

What OSes are you seeing the problem on? (Check all that apply)

macOS

What OS versions are you using?

OSX sonoma 14.0

Relevant log output

N/A

Any other information

Seems to only affect guest machines

Oh this is so weird. If I use a web-ui on barrier server host, it solves dosbox https://archive.org/details/win95_in_dosbox as an example. So it's purely related to clients.
