Hello,

Sometimes when I zoom a model (like the one in the picture) the application freezes for seconds and even minutes.

Otherwise it works just fine.

What could be the problem?

Thank you

It is hard to say what causes the freeze - the best way to find that out is to press pause in the Visual Studio when the freeze happens. This will stop the execution of the application and you will be should be able to see the call stack where the application is - you should observe the Threads window to see where the threads are. Also it would be good to have "Just my code" option in Debugger options unchecked so Call stack will also show you the call stack that is not "your code".
