This bug is happing to me too. This is a fresh (Fully patched) install of 8.10 (The bug was there before I reinstalled 8.10). This happens when using a Mouse or the Trackpad on my Laptop. The "Accessibility" option is NOT activated and Mouse gestures are NOT installed.)
I've noticed a slight pause, when right clicking on a link to open on a new tab or window, just before the right click starts to act up. When i notice the pause I usually solve it by 'Right clicking' on an empty area of the screen to get the "Back", "Forward" ...etc menu then 'left click' on another area to remove the menu. After that the Right click works fine for another 10 or 12 right click's on links. -- [MASTER] right click (with button release) might activate random popup-menu-item https://bugs.launchpad.net/bugs/187313 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
