Issue Description:
Initial display of new non-cached movie poster thumbnail on 'On Deck' or 'Recently Added' Home screen will more often than not appear with a garbled pixel edge on the right hand side. After thumbnail has been cached and is being displayed from the cache the garbled edge is gone. The width of the thumbnail provided by the Plex server appears to be a factor in the garbled edge appearing. I so far have been able to reproduce the issue with thumbnails that have dimensions of 213x320.

Reviewing the debug log appears to show that OMX.broadcom.resize is used when displaying the image initially provided by the Plex server but then is not used when displaying the cached version of the same file.
