Nobody else seems to be reporting this, so I guess it's down to my setup in some way, but when I run vim from a konsole window under KDE 4.3.3, I find that the konsole screen messes up during the session (feels as if it is writing with background colour on the background or something) and even when you leave vim by typing the right exit commands, display remains upset (most often confined to leftmost 20-30 columns). Konsole "clear and reset" does not help, I have to close the session and start a new instance.

Maybe connected to the konsole settings I use which are "black on light yellow"?

Should I have something in by .vimrc or konsole configuration to fix this ?

Thanks.

Is this problem only when you use vim or if you do anything from the prompt like: a long recursive directory listing, view a text file with more, ... I had a similar problem when KDE 4 first came out. After a few updates the problem went away. I now run KDE 4.4.5. You might try update to a newer version of KDE.

Do you have any statement that messes with the terminal (especially
the lines or columns) in your vimrc ?
