This shader https://gist.github.com/igv/a015fc885d5c22e6891820ad89555637 (5th
of September revision, crossbilateral only) crashes the radeon driver and
brings the whole system down. Previous version does not.

1. Get mpv
2. Create ~/.config/mpv/shaders/crossbilateral.glsl
3. Add user-shaders:"~~/shaders/crossbilateral.glsl" to your mpv.conf 
4. System will crash
