Subtitle difficult to download in Kodi 17 (beta 3)

Hello and thanks for reading. I am testing Kodi 17 beta 3 on OSX 10.11 (El Capitan) and I see when I watch a movie from my harddisk it’s very difficult to go to subtitles menu. It’s the third pictogram on right below side at the player. With the mouse I try to go to the menu which pops up, but it moves to the right of the screen where it disappears. When the subtitles are already activated by the switch, the menu is normally reachable by mouse pointer. It happens also with beta 2.
It works fine by using the arrow keys on the keyboard. Before I will try to send a bugreport, I will know if this happens to other users of Kodi 17 beta 3 too. Kodi 16.1 works fully ok. Thanks so much
