- Disable cascadeFindFirstFit The cause of segfault, so reference to null pointer std::sort （belowSorted.begin(), belowSorted.end(), compareTopmost）; I got the log message using compLogMessage() function. You can got the message in console, to do this, type #compiz --replace ccp
- Fixed to cascadeFindNext function If we go off the screen, start over with a new cascade. I fixed to error condition： cascadeY + winHeight > workArea.bottom() There was an logical error on calculating of window position(x,y) e.g. 465+434 > 900 in this case: error occured(no next to cascade) In my opinion, First, cascadeFindFirstFit function was not completed, so useless Second, my patch is tricky, so need to improve. Good review for this patch would be welcome! ** Patch added: "cascade_mode_segfault.patch" https://bugs.launchpad.net/compiz/+bug/1302098/+attachment/4217889/+files/cascade_mode_segfault.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1302098 Title: Windows cascading mode cause segfault Status in Compiz: Fix Committed Status in “compiz” package in Ubuntu: Confirmed Bug description: I found a critical bug in compiz, the x-window-manager.
