FOUND SOME... Well I've managed to reproduce this bug - in a "scientific manner".
I tested window behaviours when the Compiz crashed. Is not about programs - I can stop Compiz using any aplication that can open a FULLSCREEN window. For exmple Nautilus. By default I "trained" my folders on the desktop to open their windows at 50% from desktop not full screen Now I put a folder on fullscreen mode - I close that folder - and next time when I open this folder (Nautilus memorize last size and position of windows for each folder and for some applications) - Compiz gone. Same things for other applications. -> When in non fullscreen mode - ALL OK. -> When any folder OR application was opened directly in fullscreen mode - Compiz die. About bug behaviour When I launch some programs - they wont open windows - they crash Compiz then stop. After Compiz gone and Metacity come - Applications work normal ( open ..close ..etc ). For the latest testing series - I used UNREDIRECT FULLSCREEN WINDOWS option from Advanced Desktop Effects Settings -> General Compiz Options -> General - but no better results. I made I think 30 tests - with the same predictable (from now) behaviour. I hope this will help ** Summary changed: - launching applications kill stop compiz + launching applications kill compiz -- launching applications kill compiz https://bugs.launchpad.net/bugs/138424 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
