Are H.265 videos stuttering or permanently stalling?
Not much happened with #0107 apart from some locking changes. There was a deadlock introduced but there was a fix in #0108.

I tried a few H265 samples with #0108, no problems - stutter free - but that is without subtitles.

I then added a simple (non-insane) ASS subtitle and it introduced occasional stutter, so subtitles do seem to be a small issue.

Example video: Friends.h265.Sample.mkv (11MB dropbox) with Friends.h265.Sample.ass subtitle file (this isn't the correct subtitle file for the video, just a subtitle demonstration so don't worry about the words having no relation to the video!)

#0106 H265+ASS seems to be stutter free with subtitles (assuming you can avoid a deadlock!)
#0107 H265+ASS deadlocks almost every time at start of playback
#0108 H265+ASS occasional stutter, seems to rarely deadlock (although it did once)

Can upload debug logs if required (ie. if not reproducible).
