VcXsrv Windows X Server

As a non-programmer of X display software I cannot judge the code, etc., so I can only really review as a user - ie, ease of use, documentation, etc. The software may be a technical marvel, but if key features/functionality do not work, there is no documentation available on said feature(s), and no answers from the developers for most/all questions posted - some as long as 2-3 years ago... then it doesn't really matter how awesome the software may be in other ways. There is little to no documentation of anything for this windows X server. A major show-stopper for usability of this software for me is the problem of the mouse cursor disappearing while it is over the remote X window/application regardless of which type of launch you do. The mouse works fine elsewhere in Windows but as soon as you place it over any part of the X window, it vanishes, making it useless for myself or more importantly for my wife who I am trying to set remote access to an X/Linux app up for. (for the record, I'm trying to use it to run virt-manager remotely from a Windows 7 system). The remote X display rendering is horribly slow, and it is not due to lack of display/GL/drawing or any other video card hardware capability on the client side. No need to provide specs of the video cards on the client as I am not trying to impress anyone. Remote display on the same client FLIES running Linux and SPICE. Obviously, remote X display != SPICE, but if there was any documentation, support, or even semi-intelligent discussion of problems with this software available or evident otherwise I could read it and try to work through the problems. With basically nobody's questions about ANYTHING related to this software answered for a period of years, I would be a fool to expect things to be any different for any questions I post. Thanks but I'll try something else to accomplish what I need. Have spent enough time on this approach.
