KSP 0.90 x86 on Windows 8.1 x64

In the editor scene (the SPH is easiest to replicate), holding down the mouse scroll wheel (or MMB) and panning the camera around can cause the camera to wiggle and vibrate if the cursor passes over certain UI window. So far, the UI elements I've found that trigger this are the parts list, More Info window on a part in the parts list, tweakables, staging list, Save/Exit/New buttons, Action Group/Parts/Crew buttons, the AppLauncher and the editor gizmos - the vessel name field doesn't trigger this. The amount of vibration appears to be dependent on the speed at which the cursor passes over the UI element.

This behaviour was not present on KSP 0.23.5. It was introduced in 0.24.2 at the latest (though in a more exaggerated 'wiggle' form, rather than vibrating) and continued into 0.25. While the wiggle has been dampened into more of a vibration in 0.90, it's still present.

Please see this short video that demonstrates the bug and it's reproduction steps:

(at 12 seconds, you can see another bug/feedback report - when deleting the root part for a craft and a new root is selected, the part appears too high up and out of camera view)
