Version: (using KDE 4.2.0) Compiler: gcc (Gentoo 4.3.3 p1.0, pie-10.1.5) 4.3.3 OS: Linux Installed from: Gentoo Packages Steps to reproduce: 1. open konsole 2. fill the shell with some input to get to the bottom of konsole (e. g. seq 1 25) 3. execute printf foo && read (but do not finish the read command) 4. open a new tab 5. switch to second tab 6. open search dialog (the thing that shows up when pressing Ctrl+Shift+F) 7. switch back to first tab The foo line is now missing. The cursor is at the right position, but the text foo has been deleted (it has not taken background color, as it is also not possible to copy it any more). (I did not test any shell beside bash)
Interesting bug...
The bug is still there as of KDE SC 4.5.0. There are some other ways to reproduce this, see Bug #192221.
