OK, problem solved ..need to point now to Compiz Developers The strange behavior for Fullscreen opened windows (Nautilus or other applications) was caused by a Compiz plugin named PLACE WINDOWS under WINDOWS MANAGEMENT SECTION.
This plugin has 4 possible states = 4 possible ways to put a window on desktop when this window is generated. 1 Centered 2 Smart 3 Maximize 4 Random The subject of this bugreport is RANDOM mode. When RANDOM mode is activated - this plugin try to calculate a random X and Y start points for the new generated window. This is in oposition with the case when a window try to start in fullscreen mode. I will try to note this to plugin owners - maybe this mode can be disabled for windows opened in fullscreen mode. -- launching applications on fullscreen 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
