Vista - MouseMove event in Viewport3D

I am experience a problem capturing MouseMove event in Viewport3D - it looks
like this event is either buffered for some reason, or is scheduled from
low-priority thread, or something like this. When an application starts I
simply don't get this event for some time, but after a while it goes
through. I handle this event in other UI elements.

I meant "I handle this event in other UI elements without such problem."

How many triangles are in your scene? Depending on the complexity of your
scene and models, it can take some time to calculate the intersection of the
pick ray with all the triangles in the scene. Mesh bounds are calculated
lazily and cached to improve future hit testing performance (which may
explain why there is a lag at first).

If your scene is not very complex, I would be interested in learning more
about your scenario so that we can understand why you're seeing this
behavior.
