Null Pointer Exception

As the title says, sometimes I see the taskbar animations stutter a little bit on my 144Hz monitor, especially when switching between thumbnail previews of different windows or after closing a window (when the icons animate a bit to the center). I am not entirely sure what causes this. Chrome has a similar issue with its tab animations -- turns out they hardcoded 60hz refresh rate in their source code so I had to patch and maintain my own build. This past experience makes me wonder if similar thing is happening here. Can the animation be smoother? (btw the experience has been awesome otherwise great product!)
