1. Open a new terminal. Make sure the current row/line is well above the

2. Play a video file file with mplayer. (standard output, so that
audio-video sync, etc. is continuously updated)
3. Note urxvt cpu-usage
4. Press some commands in mplayer. eg. toggle play (space) multiple times
until the current row is the last/bottom one.

When the row being updated by mplayer is not the last/bottom one, urxvt use
much more cpu. I've observed this a long time. I use ion3 as a WM though,
and haven't tested under something else.
This happens both for plain urxvt and the daemon client.
Debian package version of xserver-xorg: 1:7.6+8
urxvt version(s): v9.12 - released: 2011-06-29 and latest (2011-09-23)
mplayer used to output the sequence to clear to the end of the
terminal, instead of the clear to the end of line sequence. You
probably still have a version that does that. I'm not sure if clearing
the whole terminal should use a noticable amount of cpu either though.
Thanks, then I'll just wait it out
I guess it makes sense that it's mplayer and not urxvt. ion3 is a tiling wm, so
sometimes the terminal is quite large. I think I've observed it on more
normal-sized terminals too though.
