[Bug 46257] PrintWindow returns black image

--- Comment #5 from Stuart Axon  ---
Hi,
   Here is some CPP code that grabs a screenshot of a window.
It's not the same as the python code, but grabbing screenshots does fail under
Wine.

Thought I had an MFC version (a port of the python code) working before, Xmas
.. but definitely isn't working now, so I've commented that out (and probably
broken more things).

Code is a bit of a mishmash of C/C++ idioms as it's code-by-googling

You can run notepad then capture it like

capture-window -l Notepad
