I'm getting some validation errors while running my application.
It seem that occasionally WGPU cleans up a command buffer that hasn't actually finished yet.
I'm not sure where this is coming from, there's a log included below. As far as I know I wasn't getting these errors yet when I was working on #429, but because these errors happen infrequently I can't be 100% sure.
