Hi, I am still having the this problem. The following URL will show examples of the problem.
www.kde-forum.org/artikel/13650/The-screen-goes-wild.html
I did not make the original post, so sombody else had the same problem I did.
I did not have the problem with previous version.
I did not have the problem with Ferora Core 3, but did with Ferdora Core 4
i did not have the problem with Ubuntu/Kubuntu 5.04, but do with 5.10
I would really appreciate some help.
Thanks
In all cases clicking on "Refresh Desktop" erases the lines and other problems.
