Refresh issue with GMapRoute #108

Open Al-Kashi opened 5 years ago

Al-Kashi commented 5 years ago

Hello, I have an issue with GMapRoute can than be reproduced by running Demo.WindowsPresentation: when running this demo on Remote Desktop on a Windows 2016 Server (couldn't reproduce with another setup) with a Route between two points ("set start", "set end", "Add route", the rendering is correct: image Then I close the Remote Desktop, re-open it on the same server, the window is redrawn and after a split second, the previsouly drawn route has been re-centered on the left-top corner of the map: image When moving the map by drag'n'drop, the route remains on the same left-top corner spot. Zooming in/out makes the route size change, but not its position. Thanks if you have any idea for the source of the trouble

While trying to debug the whole stuff, when examinating the GMapControl object's Non-public members, there is a slight difference before/after the Remote Desktop closure and re-opening: Before: image After: image

That being said, the way this happens and the how to fix it remains utmostly unclear.
