lets try to narrow it down:

1) does it happen only when you hit pause? (it that case it might be a
problem with frame duplication and copy on video_out.c.)

2) you said that the slice comes from an old frame, so the image is not
being overwritten right? i mean, it is more like the new image was
drawed over a "recycled" frame, but it didn't set the initial slice
pointer to zero or something?

that's all i can guess now, but i really think you should know the xshm
driver better than i...
