Description:

The video output stops when the window is being dragged. When the dragging ends the video will play normally and skip to where it should be. (If dragging for 10 seconds, 10 seconds of video is skipped)

Steps to reproduce:

1. Open the mediaplayer and open any valid media file.
2. Start dragging the mediaplayer for 10 seconds. The video freezes, but not the audio.
3. Stop dragging. The video will resume playing and skip these 10 seconds.

Expected behavior:

The video and audio play normally when the window is being dragged.

Observed behavior:

The video freezes, but not the audio. The result is that a part of the video is being skipped.

Special notes:

The audio works normally while dragging. The playback is not being paused, only the video output is freezing. 

The video shows the issue, however it is a lot easier to observe when using a file that contains an audio track.
