Hi,
using compton as compositor with this command line options fixed it for me:

/usr/bin/compton --vsync opengl-mswc --backend glx

the opengl-mswc option did the trick:

      --vsync VSYNC_METHOD
           Set VSync method. VSync methods currently available:

           •   none: No VSync

           •   drm: VSync with DRM_IOCTL_WAIT_VBLANK. May only work on some (DRI-based) drivers.

           •   opengl: Try to VSync with SGI_video_sync OpenGL extension. Only work on some drivers.

           •   opengl-oml: Try to VSync with OML_sync_control OpenGL extension. Only work on some drivers.

           •   opengl-swc: Try to VSync with SGI_swap_control OpenGL extension. Only work on some drivers.
                Works only with GLX backend. Known to be most effective on many drivers.
                Does not guarantee to control paint timing.

           •   opengl-mswc: Try to VSync with MESA_swap_control OpenGL extension. Basically the same
                as opengl-swc above, except the extension we use.

I autostart it at xfce login.

Ciao,
Tito
