Comment (by pbennett):

 == Green line at the bottom of the screen when watching video ==
 Actually there is a green line at the bottom and side on some videos. I
 notice it on 720p or 480p videos when watching on a 1808p display.

 The green line only occurs if it is using texture format YV12. There are
 two texture formats used for most systems - YV12 and UYVY. The logic for
 choosing which to use is rather obscure. It is choosing UYVU on regular
 Linux and choosing YV12 on Android. Testing shows that both formats work
 for Linux as well as for Android, but YV12 is causing the green line on
 Android. It seems to be a problem with the resizing algorithm. Changing to
 use UYVU on Android seems to solve the problem. See attached patch for the
 workaround (20180227_1100_android_greenline_workaround.patch)
