Bug with controls in full screen using openGL output

When you are using OpenGL video output , controls seem to disappear in fullscreen mode for VLC 2.1.1, 2.1.5, 2.2.1 and others before i think.

What i found, they have not disappeared, they are just invisible, but they remain active.

This problem occurs when playing some files with avi, mkv, mp4, wmv extensions randomly and all the time when playing a stream (using livestreamer for example).
