I did some digging about this issue and discovered that if a window is semi maximized, CompWindow::border is set to values of maximized window borders (left 0px, right 0px) but the normal border (left 1px, right 1px) is still drawn around semi-maximized windows.
So, if a window is semi-maximized, compiz will calculate the window geometry without leaving the extra pixel for the borders. Consequently the borders occupy the next available pixels, which happen to be in a different workspaces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986051 Title: Window management - Semi-maximized windows have 1px borders drawn on adjacent workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/986051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
