If you select any of the Beatz One series of skins by Clarence the player should look like this:
But if you have a high resolution monitor and the display scaling is set to 125% as below (this was the out-of-box Windows setting)
and you load the skin this is what it looks like:
The speakers are distorted and the buttons have shifted.
There are 2 ways to fix this problem. The first is to set the scaling to 100% and reload the skin. However the drawback to this is that the screen characters were so small that it was impossible to use. You could if you are so minded faff about changing font sizes so they become usable - it took me a day to do this.
The second way to resolve the problem is to right-click on MusicBee.exe select Properties -> Compatibility and make the changes to match the screenshot below:
Be aware that if you update MusicBee this change has to done again.
