While I'm resizing a window, fvwm normally displays geometry feedback
(window size) at the top-left. But when "xcompmgr -c" is running,
such information is no longer displayed.

Note: geometry feedback (window position) is also displayed in the
same way while a window is moved, but in this case, xcompmgr doesn't
prevent the display.

Same problem with compton (with or without -c).

This bug is due to the method fvwm uses to display the geometry
feedback, and is largely outside the control of compton.

Please see the discussion in this upstream bug report[0], as well as a
workaround (using fvwm event scripts and compton's dbus interface to
disable redirection while resizing is taking place).

Please try this workaround and let us know how effective it is.

If it works, I can't see an easy way to add it to the package, but it
might be worth a mention in the manpage.

Grrr... I didn't receive this mail:

So, reassigning to fvwm.

Hi,

Thank you for the bug report.

Have you tried the workaround suggested by Scott Leggett:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727549#25

If the workaround works, please submit a patch and I'll apply it to the package.

The dbus command is currently failing on my machine. I suppose
that the compton patch hasn't been included in Debian.

As this is specific to compton, this wouldn't really fix the bug.

Is there any reason why "move" information is displayed on my machine,
but not the "resize" one?

Hmm... this is because I don't have an opaque resize.

I looked into the Debian compton package version 0.1~beta2-1, which is
currently in both Jessie and Sid. The package does include the dbus
patch from [1].
You are correct. If the dbus workaround works, then users of compton
have to individually redefine their move/resize Fvwm bindings to
include the workaround.

With or without the workaround, I don't think this is fixable in Fvwm.
I'm therefore tagging this wontfix.

OK, I now understand. But IMHO, the best solution is to use opaque
resize. This is superior to non-opaque resize, as one can see the
result in real time, and nowadays the machines are fast enough to
support it.
