Hi Adrian,
Your mapping app seems really responsive under Remoter for me. I tested in Windows 7, and at 16bpp. Not sure why you're seeing a big slow-down.

PS: For the weird color issues, please try disabling "Bitmap cache" under Advanced settings.
PS2: I can see what slow-down you refer to in your app. Especially now that I maximized it I'll look into it. Thanks!
