Full Screen Skips with Subs

[VanishingHope]

Searched the forums but didn't really find anything.

When playing any file which is 1280x720 using H264 in full-screen mode, BS.Player freezes and stutters severely when subtitles are displayed. Thought may-be this issue was caused by a new file but I watched some files I had from a year ago (which I watched with I believe 2.54 without issue... H264... 1280x720... full screen). The "old" files did not work now either.

What's more is I don't believe there's a pause if the subtitles don't show. Truth-is, using the submenu and unchecking Primary Subtitle (turning it off) didn't work. Also checking "Disable subtitles" under the Subtitle options didn't work. Both of these cases still showed subs. However, with the main options window up the subtitles do not show on my PC and there wasn't a stutter.

One last oddity... if I expand the window to cover my entire screen (still running in windowed mode), I do not have any stutters.

Any help is appreciated.
Thank you,
