After a testing session on #ubuntu-mozillateam with Alexander, we came to the conclusion that the bug is shy and appears quite randomly.
The best way to reproduce it is to open many tabs of different websites (~30), and look at the autoscroll hover cursor in each. Some will have the correct "move" cursor (which looks like a hand in the Ubuntu Human theme), and some will have the incorrect "resize up" cursor. A website that showed up with the wrong cursor on my machine did not exhibit the same problem on another tester's machine. -- autoscroll shows the "resize up" cursor https://launchpad.net/bugs/82168 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
