If DXVA is disabled, then sometimes no video is shown, but audio is playing

Hi there,
I discovered that v17 final sometimes doesn’t display videostream but audio is playing when DXVA2 hardware acceleration is disabled by user for his/her reasons.

-> Black screen and display statistics say vq: 0 % which should be over 90 percent. If I then press x on keyboard to stop playback and press enter to play the same file again it sometimes works.
