Gmplayer with vdpau stuck

gmplayer with vdpau driver gets stuck randomly when opening the popup menu in fullscreen mode. The card is “NVIDIA Corporation GK208B [GeForce GT 710] (rev a1)” with 390 legacy drivers from Debian unstable packages. The video codec is software one (ffh264]. I could not reproduce it with nvidia logging on. It has 4 threads, all stuck at poll call, one thread in libvdpau, one in mplayer gui, one in glib and one in libpulse.
