Comment (by low-batt):

 The proposed fix works for me.

 I pulled the current FFmpeg master (36a986d), applied the patch and built
 ffplay. I confirmed playing the file
 [https://stvinmotion.com/visualove/Samoan_20_Ring_Into.zip
 Samoan_20_Ring_Into] no longer shows the horizontal lines.

 As a side note (unrelated to the proposed fix), I now see a continuous
 stream of warnings emitted from ffplay while playing the video:
