Live Clock Causes Directory Flashing In URxvt & XTerm

Hello zsh Team,

These are my specs;

Slackware 14.1 x86_64
xorg-server-1.14.3
Nvidia GTX660M - nvidia drivers 331.67
zsh-5.0.2
rxvt-unicode-9.20
xterm-297

I'm using this option to have a live clock in my ~/.zshrc

TMOUT=1
TRAPALRM() {
     zle reset-prompt
}

In URxvt it constantly flashes, in xterm it flashes on and off more
randomly, and I also noticed in xterm the entire directory appears to get
brighter as well as flashing.

So as example, 'cd /etc/' then tap tab to see the directory, try this in a
directory with a small amount of directories, or open the term full screen
to see a huge directory, but play with it, and at that point the terminal
starts flashing.

I have not been able to find a fix for this, the only temporary solution is
to increase the time, as an example below;

TMOUT=10

Then it's not so noticeable, around every 10 seconds you see a flash, but
this is also not good because when the time changes, the terminal will not
change till 10 seconds later, there's a lag doing this.

I hope the zsh team can fix this problem, and if you need my help please
contact me.

I'm attaching a copy of my ~/.zshrc and I created a short video called,
zsh_flicker.m4v that you can download from my dropbox;

https://www.dropbox.com/s/o0gmkpbxp8f42u3/zsh_flicker.m4v

If you look carefully you will see the directory flashing every second.

Thank you much for your time and help in this matter.
