Movement of MPV window causes artifacts

[dccsillag]

How to replicate:

• Open MPV with some video; it can either be playing or paused.
• Open some other window (say, st) to the left of MPV.
• Swap the two (terminal goes to the right, MPV goes to the left); now the terminal is completely obscured by artifacts of the MPV window.

Note that if we do the reverse -- that is, start with MPV on the left and terminal on the right -- everything works fine. This is probably because things that are lower on the XMonad (the WM I use) stack are at the bottom of the z-order.

Update: it appears that removing the size animation code solves this.

Solved with the new size animation content interpolation code.
