enabling subtitles with h265 mkv files interferes with UI
Description
When I enable subtitles in an mkv file, the interface becomes invisible after the first line from the subtitles is shown.
What I mean by invisible is, pressing left or right arrow on the TV remote will seek as expected but there are no on screen indicators anymore. When I press up or down arrow, I can hear the audio cues from the interface but I can't see it. Volume buttons work but I can't see the slider.
Backing out of the file and playing it again fixes the interface but also resets subtitles to disabled.
This only seems to happen with h265 files. h264 files don't cause this problem.
