Kodi 17.1 on Pi3 : Movies are played at background

Hi There,
Just installed my new RPI 3 (Raspbian jessie with pixel) downloaded kodi app as a regular Linux app.
The things is, that after I start a movie (say on exodus), it is loaded but it isn’t being played.
I see a small triangle (like “play” button) at the right upper kroner of my screen, after I press the movie is played.
Have the same version on my Windows machine and no that kind of issues.

Please advice.
