White box around pointer when over EVE clients

Thanks for the reports everyone. We’re going to try getting an internal reproduction on this with the latest Windows updates.
There is something unusual happening here, as we’ve not changed the code behind the mouse cursor tracking for a long time.

If you are experiencing the problem, can you file a bug report when it happens from within the client by pressing F12. It would be very useful if you would paste this thread URL in and mention me.

Thank you
