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?
Solved! Go to Solution.
Compatibility mode isn't a long term solution. This problem has been fixed for me since the 17134.191 build, but it seems people are still having problems. The October Update 1809 was out for a little bit until Microsoft found out about people's personal files being deleted after upgrading, so they have pulled it for now. blacklord049 said the bug has been fixed for him on 1809 (he got the update when it was still out), so I think this issue should be completely fixed for everyone once the new update gets rolled out again.
