Image isn't found on full screen mode window

[kenorb]

I've BlueStacks app (Android emulator) and this code works when the window is not in full-screen:

app = App("BlueStacks")
app.focus()
region = Region(App.focusedWindow())
region.click("JTi.png")

But the script fails to find the image, when the app is in full screen (in another workspace).

The error is as follow:

[log] App.focus: [28084:BlueStacks]
[error] script [ MyScript ] stopped with error in line 4
[error] FindFailed ( JTi.png: (80x89) seen at (1772, 922) with 1.00 in R[0,0 1920x1200]@S(0) E:Y, T:3.0 )

I'm using SikulixIDE 1.1.1 on macOS Sierra.
