Folks,

I have an interesting problem -- not sure what's causing it.

Using xfce4 + compiz -- nothing too fancy. When I open an xterm and
start typing, I start getting 'artifacts' (specifically green lines
between the various letters I'm trying) in my xterm.

The only way to "fix" this is to either:

(a) move the window (doesn't solve the problem if I start typing again
in the terminal)
(b) resize the window (this will solve the problem for all text
present and future entered in terminal)
(c) ...uhmm, nothing else

I thought it was a font size problem -- my Xdefaults is configured to
have some pretty tiny fonts.

XTerm*faceName: Monospace
XTerm*faceSize: 10
!XTerm*faceSize: 9

Modifying the font size, however, did not resolve the issue. The
problem persists.

Thoughts / ideas? This is happening on all the computers I've recently
built, not just this one.

What video hardware and driver are you using?

I used to see (different) rendering artifacts when using the ATI fglrx
"blob" driver and aterm -- but not other drivers nor other programs. I
switched to the radeon driver, and haven't had any issues since.
Actually, the last time I tried the fglrx driver, I think the problem
had gone away.

Using various different hardware configurations -- my laptop has a
Intel 915GM. The same thing happens on my iMac which has an nVidia
card.

I tried to take a screenshot of the issue, but the artifacts do NOT
appear in the screenshot.

Hum, does http://www.nvnews.net/vbulletin/showthread.php?t=150390
help? (It suggests that it is a problem with Compiz 0.8.6 against
nVidia and Intel drivers, and a work around is to downgrade to 0.8.4.)

Cheers,

This is actually precisely how the artifacts appear on my screen. I
will try a downgrade and report back the results.

I wonder if there's a compiz bug out there to report this problem.
