Boxed Renderer Mouse stuck

Not sure if this has been mentioned already but seems like a bug?
Windowed DX renderer gets his mouse stuck.

Patch attached.

Hi,

Right, happening on beta 29 and beta 29.2 only with “in a box” renderer".

Yes sorry, box, not windowed :)

Btw I don’t why, but seems not to be so important for me.
