Fwd: Netbeans platform rendering error on win10?

Hi,

In our product (based on NetBeans IDE 8.0.2 (Build 201411181905)), we've
had some users, but far from everyone, that experiences a graphical error
such as in the included picture. When the problem has started, it renders
multiple graphical artifacts that looks like hovering versions of the
original TopComponent.

It seem to occur when the user interacts with an instance of an
implementation of an  AbstractCompletionEditor (types text in a textfield
that provides code completion) and I can't seem to find a pattern. Other
than that it has only been reported on Windows 10. And we have windows 10
computers of our own that does not have this problem... It reminds me a lot
of the good old days in windows! :)

I'm just curious if you have heard or seen anything like this?

Thanks!
