Unfortunately, bug 1019337 has not solved my problem (I have updated and even rebooted today).
However, when I run your trace commands, the nature of the problem changes; instead of the window decorations disappearing altogether, the close, minimise and maximise buttons did. And then I cannot cause it to crash. Still having a problem with breakpoints: Function "_XError" not defined. So, I just answered "y" and that gave me a "bt" (attached). So, I'm not sure that it will give you a true reflection: without running your trace, the window decorations disappear; whereas running your trace, only the close, minimise and maximise buttons disappear. ** Attachment added: "bt trace from _XError" https://bugs.launchpad.net/compiz-core/+bug/993265/+attachment/3219604/+files/Paddy%20Landau%20_XError%20trace.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993265 Title: Wine breaks window decorations for all applications (gtk-window- decorator crashes) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/993265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
