I was able to use QWindowCapture to successfully capture some of the
windows. For example, in the screenshot above I've captured a Finder
window. It had to do with needing to call self.window_capture.start() again
after I've set a new window.
My goal is to capture my PyQt window itself which is generating animations,
but I'm not seeing the window listed as a capturable window in the
QWindowCapture.capturableWindows() list. Note that the PyQt window is
called "TESTING TESTING", and it's not in the list. I've checked all these
capturable windows, and none of them are the PyQt window. *Is it just not
possible to capture a PyQt window with QWindowCapture?*

As QWindowCapture was added to Qt v6.6 then you need PyQt v6.6 at least.<br>
