Clipping windows to the side leaving blank area

[Tatranskymedved]

Hello, I've observed a visual issue, when I tried to clip a window to the right side of the screen (Windows 10), there is a blank area left around the window, where we can see in the background. Spotify window "thinks" that it's clipped on the side as it should, which means there is some "invisible border" where we can see through.

Brief description of the issue:

Steps to reproduce the issue:

1. First open spotify, clip to the right side of window (WIN + right arrow)
2. Open other window, clip to the left side of window (WIN + left arrow)
3. Now You can see that there is empty space in the middle

Windows 10, not related to account version, current Spotify version: 1.0.72.117.g6bd7cc73
