Since discovering VLC for the first time I have found it to be an extremely reliable media player on both Windows and Linux systems... BUT of all the Linux distros that I have tried and used from past to present I can only complain about VLC's performance and reliability on Manjaro.
I don't know why, but compared to my experience on Windows and all other distros (Ubuntu, Debian, OpenSuse, Slackware) it is significant more sluggish, would freeze on occasion and flash black or white every time I adjust the system volume or switch between windows on Manjaro XFCE.
Don't get me wrong. Even with these problems I still think it's a rock solid media player. It just doesn't pair up well with Manjaro XFCE in my case(s). Luckily it seems this "bad pair-up" is only true for VLC on my systems. I've started using SM Player and it works like a charm. It would still be nice to know why VLC is so problematic on my systems and I welcome some speculation although I don't think it worth fixing if I can just use another media player instead.
