           Summary: scrolling smears or distorts information (on only KDE

           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

screenshot of Konq after the scroll wheel has been used

Version:           unspecified (using KDE 4.5.0) 
OS:                Linux

When I am in a KDE application and I use my mouse scroll wheel to scroll a
window the information is so distorted or smeared that I can't read it.  Some
time if I scroll one line at a time it is okay. Other versions of KDE4 also had
this problem BUT version 4.4.4 had no problems.  This occurs even if
compositing is turned off.  It does not occur though if I use a different
window manager and scroll the same kde program that consistently gives me
trouble when running KDE 4.5.  It makes KDE unusable.

Reproducible: Always

Steps to Reproduce:
This is done with a GeForce4 nVidia AGP card.  Open KDE app while running KDE
4.5 and use the mouse wheel to scroll.  

Actual Results:  
See attached image of Konqueror... it is not too bad... some time it is so bad
that there is just vertical lines (smeared).

Expected Results:  
Scrolling with mouse wheel so that info continues to be readable.

It appeared to me that the upgrade did not change the xorg file as it had a
July date and I installed 4.5 in August. (I am using the same nVidia driver as
the previous version.

I will provide you with any other information to get this problem solved. 
Version 4.4.4 was perfect so it can be fixed.  I classify this as major because
it renders KDE unusable for me.
