This bug only happens to helix device. I never tested it at other HDPI device. But it doesn't happen to other 320x480 devices, like Inari, Ikura, Unagi, etc.

STR:
 1. put videos into device, the last modified date of video files must have different year and month, like:
      video-a.3gp: 2013-09-12 hh:mm:dd
      video-b.3gp: 2013-10-16 hh:mm:dd
      video-c.3gp: 2013-08-01 hh:mm:dd
   So that, the video app will put video-a, video-b, and video-c into three groups.
 2. open video app
 3. scroll with your finger at the position of video-a <== slow scroll.

Expected: scroll is smooth.
I had tested the code in gaia side. If we change the border-top[1] from 0.1rem to 0.2rem or remove it. The scrolling becomes smooth.

This video is the original setting, border-top: 1rem. The scrolling is not smooth.

border-top: 2rem

This video is with 2rem in border-top. The scrolling is smooth.
Testing at:

PVT Build: master build for helix 20131002040206
