Comment 3 for bug 1904135

@ronso0 The related bug you remember is #1882474 but it was partially solved.
It was solved only the part of being unable to enter-exit fullscreen. This was only solved.

The wrong appearance of the rest checkboxes of this View dropdown menu as well as their incorrect operation after enter- exit fullscreen wasn't solved.

In linux Mint 19.3 (bionic) V 2.3.0 git 7749 downloaded today,
all options and their related Ctrl # shortcuts

show skin settings menu ctrl 1
show microphone sevtion ctrl 2
show vinyl control section ctrl 3
show preview section ctrl 4
show coverart section ctrl 6
maximize library space

continues to do nothing after change the state of fulscreen.
You have to restart the software in the new state (full or windowed) to resume operation of the above checkboxes and their shortcuts.
