Description
get_current_texture seems to be leaking memory on OSX when the application is not visible on the screen.

Repro steps
Start a wgpu application, move it behind something or to another desktop so that it's not visible, check memory usage.

Extra materials
I'm using this method to run it with tokio: https://gist.github.com/FredrikNoren/7c3535b11e99e8fcd8dd3d55f9a934a2
I used cargo-instruments to profile the application.
