Comment 1 for bug 1483581

Hello and thanks for the report. I am the Debian maintainer of Byzanz. It is completely fine to report bugs to launchpad.net if you are an Ubuntu user. However you often get faster responses when you report to Debian's bug tracker or to the upstream developers directly.

Though in this case upstream has been pretty inactive for the past years and Byzanz mostly receives language updates.

I can reproduce this bug when I try to record videos without the -c flag, e.g.

byzanz-record test.flv

Without some interaction it will basically record nothing useful at all. You can avoid this behaviour by using the -c flag.

byzanz-record test.flv -c

This seems to trigger screen repaints. I can't reproduce this issue with gif files, the default file format, here it works even without the -c switch.

So it looks like you can circumvent this issue by using the -c flag without having to rely on external tools for screen repaints.
