This bug also affects me. The suggested workaround works for me. I figured out how to reproduce the bug everytime (at least in my case):
1) Maximize a window to the secondary monitor 2) Unmaximize the window on the secondary monitor. 3) Resize the window so that it is too big to fit in the primary monitor 4) Drag the window to the primary monitor (because it is too big to fit, part of it will be in a different workspace) 5) Maximize the the window Result: Even though the window is almost entirely in the primary monitor, it maximizes to the secondary monitor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947025 Title: Multi-monitor - Windows maximise only on the secondary display To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/947025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
