Does this go away if you switch off "inhibit the screensaver" in
Preferences->Fullscreen? It helps on my system.

Subtitle rendering happens in software (via LibASS) in screen
resolution. This should be fast enough, but I don't use subtitles
myself so I seldom test this.

Can Mplayer or VLC play the same half-width SBS video plus subtitles in
your setup without frame drops? If so, Bino clearly has a performance
problem somewhere that we should find and fix. If not, then the
limiting factor is likely LibASS (which mplayer and VLC also use), and
there is little we can do about that.

This is already available under Preferences->Current Video Settings.
