VLC choppy video in fulscreen while using X11 output

Hey guys, I have a problem with video in Ubuntu Mate 15.10, on 15.04 it worked perfectly fine. I use VLC as my default video player and while the XCB output works perfectly fine it blurs the subtitles if the video source is not HD. In 15.04 I used X11 as my default video output and it worked perfectly with clear subtitles. On 15.10 the video is fine while playing in the window, but if you switch to fullscreen it becomes very choppy. I have the exact same configuration and drivers as in 15.04. Using mobile Radeon HD4330 and Compiz as my window manager with default profile from 15.04. Does anybody had a similar problem? Can I fix it?
