Sure Christopher! A screencast couldn't record the graphical glitches, so I recorded a video with my phone and attached it to this comment.
In the video I have gnome-terminal open. At the start, I press and hold the 'A' key on the keyboard and move the mouse cursor *inside* the terminal window. The cursor is constantly being hidden and shown, and the graphical glitch is visible. Then I move the cursor to outside the window. The cursor isn't hidden and the glitch doesn't occur. Then I move it back to the window. ** Attachment added: "screencast.mp4" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1585329/+attachment/4733154/+files/screencast.mp4 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1585329 Title: Sometimes a black rectangle appears briefly under the mouse cursor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1585329/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
