DrawObject.Bind does a heck of a lot more than simply binding the event type to a handler. (Like creating and/or updating bitmaps to be used to aid with hit testing, creating a pen and brush, etc.) So it’s not too surprising that in some cases it could get… um, I guess congested would be a good term. Especially when many of those operations will require a round trip to the X-server like on a Linux build.
OTOH, it would probably be possible to streamline that, or perhaps defer some of it until it is actually needed, and end up with some performance gains, if somebody felt like putting some effort into it.
