[1.19.1] qmlglsink on Windows

[Nirbheek Chauhan]

Hi Ilya,

If the same code worked in 1.18.x and crashes in 1.19.1, that does
sound like a regression. Could you please file a bug report about
this: https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/new

For quick diagnosis, please include a more complete backtrace with
line numbers. Also, a self-contained test app that reproduces this
would allow us to figure this out much faster.

Cheers,
Nirbheek
