Windows toolbar showing in fullscreen mode

Hi, I have a problem with my project build in fullscreen mode. When I launch the game in fullscreen my windows toolbar is still in the bottom of the screen and it will not disapear after game is loaded. Any idea why this is happening?

(project was created in unity 5.4 then upgraded it to 5.6
also I’m using post processing effects on my cameras
and I’ve imported EasyRoads3D assets where I had problems with Unity Editor to generate game build, but I already fixed that by moving editor scripts to the Editor folder)

Well nevermind I fixed it just by restarting my pc. It was propably problem on my side because every build is now running without any problems.
