Version: 1.3 Beta (using KDE 3.1.93 (3.2 beta 1), Gentoo) Compiler: gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r2, propolice) OS: Linux (i686) release 2.4.20-gentoo-r7 I noticed a bug in Konsole which leads to a wrong painting of the background... To reproduce it: - switch to a transparent Konsole shema. - open 2 or more sessions in the same window (using the same shema). - maximize the window. - the background of other sessions is filled with "tiles" of the old background.

CVS commit by giessl: Fix #66843. This is a workaround for a possible bug in KRootPixmap. After resizing Konsole with multiple sessions and switching to another session, the tab widget sends resize events, but obviously KRootPixmap isn't able to handle them correctly. Please try if it also fixes #71213 and similar.
