Summary:
When in fullscreen video, the cursor will disappear after a couple of seconds of inactivity when the controls hide. Unfortunately, however, it appears as though the subtitles cause the cursor to reappear; i.e. whenever subtitles show up (and the the controls are hidden) the cursor will reappear, only to disappear when there is a momentary lull in subtitles (for example, where there's no dialog). I was unable to capture this with QuickTime (which kept the cursor permanently visible) or take a screenshot (since pressing anything on the keyboard causes the controls to show up), so I hope this description is sufficient.

Steps to Reproduce:
1. Play a video.
2. Enable subtitles.
3. Enter fullscreen.
4. Wait for the controls and cursor to hide.
5. Wait for the next set of subtitles to show up.
6. Wait for the subtitles "box" to disappear.

Expected Results:
The cursor remains hidden after step 4.

Observed Results:
The cursor reappears in step 5 and disappears in step 6.
