me too.

With some videos I get an horizontal line at the bottom and with others
I get a vertical line on the right side. The line is obscuring the
video.

Big Buck Bunny[1] is a nice example: I tried the video in 854x480 and
both mp4 and ogg give me a vertical color-distorted line at the right
side. If I try the 1920x1080-version the line is at the bottom. avi or
ogg does not matter in both cases.

Here, vlc is set to automatic which chooses xvideo output (xcb).
However, the distortion is not present if I disable "accelerated video
output (overlay)" in vlc. In vlc 2.1.x this problem did not exist.
