Ok, so a bit further down the debugging road I know that this issue is related to libxinput2. I noticed that the enter/leave-notify events were firing because the panel's extents start at 0x0 but moving the pointer towards the top of the screen in combination with the sub-pixel handling of xinput2 produces negative coordinates, e.g. -0.6185, so a leave-notify event is fired, even though the panel should not have lost focus.
If you export "GDK_CORE_DEVICE_EVENTS=1" the problem goes away (this switches to the gtk2 style input instead of xinput2). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795135 Title: Window buttons are not clickable at the top of the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/greybird-gtk-theme/+bug/1795135/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
