Comment 2 for bug 417452

Apparently the problem is that maximising or restoring the window doesn't call the registered function for handling a window resize (or the function doesn't work properly); calling said function on every update fixes the problem but potentially at the cost of performance. What would be helpful would be some way of detecting a maximise or restore, so that the resize function could be called on the following update to ensure that the viewport wasn't messed up. I'm still looking into this idea at the moment, watch this space...
