Version: (using KDE 4.4.2) OS: Linux Installed from: Debian testing/unstable Packages When I start KDE, a konsole window with multiple tabs is restored by the session manager. On the tab that's active when konsole is started, the shell prompt is displayed fine. On the inactive tabs however, nothing is displayed until I press a key; the cursor is placed correctly from the beginning though.
OK, correction: things aren't displayed, not until I press a key, but until the terminal is asked to draw an additional character (while it is the active tab). I noticed the difference because I have a tab running /bin/su; while I would enter the password (which is not displayed) konsole wouldn't redraw the tab. But as soon as I hit <enter> and new characters were sent to the terminal, everything was displayed fine.
Can't reproduce it with KDE-4.7.0 Feel free to reopen if this still happens in recent version.
