i enabled opus USE flag system-wide and since than when i run vlc, it either does not show video at all or it displays the video just in small rectangle with wrong aspect ratio. i tried to disable opus USE flag on vlc but the result was unchanged so it might be affected by some library. mplayer works fine. if you need more info, just let me know. $ emerge --info media-video/vlc Portage 2.2.23

It's actually the 'qt5' USE flag for vlc that breaks full-screen. See https://bugs.gentoo.org/show_bug.cgi?id=563458
you are right. just tested clvc and it works fine. *** This bug has been marked as a duplicate of bug 563458 ***
