Yes, I did something similar: I created a new user and it didn't show
the problem, so I started to diff every configuration file between old
and new user.
After a lot of tests, this is the change in .config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml
which finally fixed my problem:
--- a/xfwm4.xml
+++ b/xfwm4.xml

Why I had "false" instead of "true"? I don't know.
Maybe "false" was the default in some old Xfce4 version? I don't know.
What's this use_compositing thing and why it affects text buffering? No idea.
Anyway: To reproduce, please set "use_compositing" to "false" and just try this simple
"ping-simulation" script:
#!/bin/sh
for i in `seq 1000000`; do
echo "64 bytes from 130.206.193.115 (130.206.193.115): icmp_seq=$i ttl=56 time=24.3 ms"
sleep 1
done
If you see two lines every two seconds, that's what it happens to me.
Thanks.
