Public bug reported: Hi,
Since a few upgrades of my ubuntu 14.10 (utopic), I have a very annoyng behaviour: almost every time I try to create a bookmark by drag&dropping the favicon to the Bookmarks Toolbar or simply move a bookmark or directory inside the Bookmark Toolbar, my mouse cursor gets splitted into two parts. Unfortunately, I can't take a screenshot, since this resolves the problem... I'm not sure the problem comes from Firefox or Xorg's/driver, so I'll post a bug report on both lists (see:https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1413572 ). Computer is a Dell Latitude E5530. More details on the software/drivers in use: Firefox 35.0 # lshw -c video *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation
