Package: xvfb
Version: 4.3.0.dfsg.1-14sarge1
Severity: important
According to the Xvfb manual page, the -fbdir option can be used to
make it expose its framebuffer in X window dump format. However, if
it is run with a depth of 32, the bytes_per_line member of the
XWDHeader structure is set to 4 * width but each line is actually
padded to 16 * width. Similarly, if it is run with a depth of 16,
bytes_per_line is set to 2 * width but lines are padded to 4 * width.
This makes the feature quite useless. It is, however, possible to
generate correct window dumps using xwd -root.
