I am experiencing a rather strange thing here. My application hangs when features are added to a GraphicLayer. We do some "magic" with scaling of symbols as well as hiding them depending on Map.Resolution. Doing a pan/zoom operation makes the application hang for up to 20 seconds. GPU load is at about 28%. CPU hardly notices any load.
The problem is really hard to reproduce, and I don't experience it all the time, and only on one machine. Deactivating any scaling of symbols does not help. I have also been working with the same application on the same machine without any problems for three days, and then suddenly it starts acting up again. Rebooting does not help. If I start the application without adding anything to the map, there is no problem. This is an oddly specific problem, which is quite difficult to explain.
This is a new machine running Windows 7 64-bit. Core 2600 GB RAM, 8 core CPU. Gainward ASUS EAH5450 Series (Powered by AMD) graphics card (will update with more exact information when I receive it).
I suspect this is a graphics card/driver issue. Does anyone have any experience with issues like this, and can help me out? Because of the randomness of the problem, I'm not quite sure where to start troubleshooting.
