Nobody seem to have my problem... Anyway, after several days I found 
that I need to add a videorate element to make the pipeline work as 
expected:

gst-launch -v audiotestsrc ! goom ! ffmpegcolorspace ! videobox 
border-alpha=0 alpha=1 left=-200 ! videorate ! videomixer name=mix ! 
ffmpegcolorspace ! xvimagesink videotestsrc ! video/x-raw-yuv, 
width=720, height=576 ! ffmpegcolorspace ! videobox border-alpha=0 
alpha=1 ! mix.
