When using Spotify on Windows 10 April 2018 update build 17134.1 or even Redstone 5 builds every second time you click the maximize middle button on spotify it is not completely going into a maximized window! And you can actually see that the very top of spotify is not fully maximized and the bottom of Spotify is cut off below the bottom taskbar as well.
I notice this seems to only happen with software that use non standard UI like Spotify and other programs I use like eM Client, iTunes and Bandicut.
Something changed in April 2018 update and remains in Redstone 5 builds. You can see for yourself by running Windows 10 April update or Redstone 5 builds. And install either Spotify, iTunes, eM Client or Bandicut. And to see the bug keep clicking on the maximized button on any of these programs and you will see that every other time you make them maximized it is not fully maximized and looks strange.
P.S. This does not happen at all with any Windows 10 builds before April 2018 update!!!
Who needs to fix this issue you guys or Microsoft?
