I managed to find my cause, it is the fusion-icon. Reproduce: 1.) install fusion-icon 2.) Set window manager to compiz 3.) Reload window manager
Appearently as fusion-icon starts at login, it forces compiz to reload. Doing metacity --replace && compiz --replace , returns alpha blending to correct behaviour. -- DRI2: (UXA) white transparency artifacts with compiz [patch] https://bugs.launchpad.net/bugs/324854 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
