Update to the above:

Did some further digging...

It appears to me that the Ctrl::ScrollView() invalidates the rectangle once and then when the WM_PAINT comes, the Ctrl::SyncScroll() causes the invalidated rectangle to be scrolled effectively doubling the invalidated area.

I think the ScrollView should not invalidate the area but wait for the SyncScroll to do it. Or are there side effects to this approach?

Any ideas...?
