[mapguide-users] Fusion: polygon in temporary layer is rendered incorrectly when partially outside viewport

[Ben]

Hi,

As a result of a digitization operation, I've added a polygon to a 
temporary layer via the mapguide dotet API (and cleared the digitization).

As you can see in my attachment, when I pan so that one of the points of 
the polygon is out of the viewport, the in-viewport part is rendered 
incorrectly. In my example image, you can see two things:

1. The top-left point is still onscreen, but is no longer used in the 
polygon
2. The bottom-left point is offscreen, but the line that appears to 
connect to it is at the wrong angle

Does anyone have any advice or workarounds? I'm using MG 2.1.0.

Thanks,
Ben
