choppy video when upgraded to alpha 3

[Casmo]

I found out about the subtitle extracting, so I tried that.
If I use the same subtitle file directly extracted from it (It's a .ass subtitle), it has the exact same lagg.
I now do have options to remove parts of the subtitles (I.e. where there are 3 lines of subtitles). Which makes the lagg disappear.

Code:

Style: Op English,Kozuka Gothic Pro B,22,&H00FFFFFF,&H00FEF1FE,&H003C0964,&H00EDD8FB,-1,0,0,0,100,100,0,0,1,2,2,2,10,10,8,1
Style: Op Romanji,Kozuka Gothic Pro B,22,&H00FFFFFF,&H00FEF1FE,&H003C0964,&H00EDD8FB,-1,0,0,0,100,100,0,0,1,2,2,8,10,10,8,1
Style: Op Kanji,Kozuka Gothic Pro B,20,&H00FFFFFF,&H00FEF1FE,&H003C0964,&H00EDD8FB,-1,0,0,0,100,100,0,0,1,2,2,8,10,10,32,1

I believe it has to do something with these styles mainly (These are specific for this anime ).
As you can see, it uses 3 subtitle tracks, which are displayed simultaneous.

Code:

Dialogue: 0,0:23:58.10,0:24:01.04,Op Romanji,,0000,0000,0000,,{\blur5\org(0,0)\fad(100,100)}umare kawatte amai yume
Dialogue: 0,0:23:58.10,0:24:01.04,Op English,,0000,0000,0000,,{\blur5\org(0,0)\fad(100,100)}A sweet dream of changing myself completely
Dialogue: 0,0:23:58.10,0:24:01.04,Op Kanji,,0000,0000,0000,,{\blur4\org(0,0)\fad(100,100)}生まれ変わって甘い夢

Maybe someone can do something with this information?

Another edit, not sure if related:
Sometimes when I start an episode, with a separate .ass subtitle file, I get to see this:

And then when I stop the episode, and restart it, I only see the timer going further.
I see nothing, I hear nothing..
