Plasma Manager Rapidly Animated Loading Overlay

In the both the standard and icons-only task manager in plasma, the loading overlay (that appears after launching an application but before the window has loaded) is rapidly animated much faster than what is intended.

Note: this bug was found in a virtualbox VM and this may possibly contribute to it, but I have no reason to believe that a VM would effect this.
