Question Flickering during text entry


Hello,
After installing Zenwalk 2.2 I have noticed this strange problem, which I can't seem to find anything about in google or on here.

The problem:
The following only happens when I'm in XFCE and not logged on as root.

Every so often (probably around two minutes or so) during mouse-only activity a small artifact will appear somewhere seemingly random on screen. Although it only appears for a tiny amount of time (The time it takes for X to redraw?) it looks a little like a short dotted underline or the lower border of a window that's about 100 pixels wide. I'd link to a screenshot but it's just too fast...

During text entry, however, this artifact appears reliably at almost every keystroke, and if one holds down a key such that it repeats, ie when deleting a string using the backspace key, it can be seen to appear in a semi-random pattern that moves up the screen, as if it were some kind of object being displayed then covered.

When in XFCE as root this does not occur at all, however, as any non-root user (I have tried setting up a testing account) this behavior continues.

My attempts at fixing it:
I have edited my xorg.conf file and reinstated sections from backups taken before the install (from Mandriva) for my keyboard, monitor and server settings, however, this made no difference. I am currently using the 'nv' driver, as the package repository for Zenwalk is offline so I can't get the official one installed, though I'm not so sure it's X that's causing the problem anyway.

I have tried copying the XFCE config files and any personal X settings (though I don't know much about X's personal settings) from root to my own account, and the flickering continued.

Questions:
  • Is this a problem with file access permissions, X, XFCE or something else?
  • How do I stop it from doing this?

Please note that I'm inexperienced with Linux. Apologies for the description - the problem defies an accurate one.

Thanks

It sounds like a problem with your refresh rate being set a little too low. Unfortunately I'm not an expert on adjusting these type of X settings.

Any experts wanna lend a hand here?
