[Mac] Color Picker window gets larger every time it's used
Three people independently reported this issue to https://musescore.org/en/node/136551, and I also verified it with 2.0.3 and 2.1-dev on El Capitan. Simplest steps to reproduce:
1. Select anything in the score, and click the "Color" rectangle in the Inspector.
2. Click "Cancel" or "OK" (it doesn't matter which).
3. Repeat steps 1 and 2.
Result: the height of the Color Picker window increases every time, until it exceeds the height of the screen (putting the "Cancel" and "OK" buttons below the bottom edge). What's even more surprising is that when clicking the edge of the Color Picker window to resize it, it refuses to be shrunk—it can only be made larger.
Analysis: MuseScore calls on the native Color Picker , so it may be that MuseScore (or Qt?) is passing information about the size of the window to the OS incorrectly.
