I got this bug in Ubuntu 14.04 64 bit (Unity). For instance, after this problem appears, I can no longer click on "Open new tab" button in Firefox (it opens the Clock/Calendar indicator instead if I have more tabs open in Firefox and the "Open new tab" button is bellow the clock indicator).
It seems to only happen if the window was maximised like Pavel Fischer said above. If I restore the window (after this bug causes the problem), the mouse resumes working correctly. If I disable "Show live previews of windows in the Switcher" (in CompizConfig Settings Manager - Ubuntu Unity Plugin - Switcher), this bug disappears (or I did not encounter it yet). But with "Show live previews of windows in the Switcher", Hot corners no longer works after a reboot (I found the solution to disable "Show live previews of windows in the Switcher" in order to keep Hot Corner working after a reboot). I have Hot Corners set (with Unity Tweak Tool) to "Window Spread" for the lower right corner. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1306550 Title: Wrong mouse-coordinates in the window after minimize/maximize of after return from fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1306550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
