[Q] Watching videos in the web browser(chrome)

hi,

Good day.

I have a problem regarding watching videos in the web browser specially in chrome/facebook(videos).
I recently flashed the official rom for i9505 which i got from samsung-updates via Odin after that I'm having a hard time watching videos in the web.
The problem I am encountered was the video hangs for a second but the sounds/audio keeps on playing then when I press the back and play it again, the video is in slow motion but the sounds/audio is good. I already search in the web but can't find a good one, I'm hoping that one of you guys encountered this kind of issue.

btw, I already did reformatting my phone twice.

Thanks in advance.
