I have now seen this on Crux, High Contrast Inverse, and High Contrast Large Print Inverse. That's all of the default Ubuntu themes now, so I think it's pretty clear: this is not theme- or engine-dependent. But some themes trigger it more often than others. I'm going to leave it open on ubuntulooks though since it definitely does affect that way more. The ubuntulooks people can mark it Invalid if they want.
Another interesting note: on Crux, which has fairly noticeable window borders, the borders are affected by this bug too. That is, when the title bar disappears, so do the borders. -- Compiz: Title bars on maximized windows frequently disappear upon various title bar events https://bugs.launchpad.net/bugs/152493 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
