Click and draw of certain links results in double mouse pointer

[Jens Herrmann]

1. Open www.efneo.com/en/hub/ with Firefox (35.0)
2. At the bottom there is a circle with a mouse pictogram and an animated arrow. Click on it with your left mouse button, draw it a couple of cm and release the button. Now you should have a double mouse pointer with parts of the circle and mouse pictogram. Here it looks like this: http://img3.fotos-hochladen.net/uploads/doublemousepohna02kloqg.jpg
3. While both of the visible mouse pointers are somewhat distorted the left one is fully functional, also in other applications. (except on one of the systems I tested, where the mouse pointer went back no normal when closing Firefox)

I tried to reproduce this on 3 notebooks with Xubuntu and succeded on all of them. I also noticed that while I can see the strange mouse pointer on the screen I was not able to capture it with xfce4-screenshooter. In the captured picture the mouse pointer always looks normal.

This appears to potentially be the same bug as https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1393169.

As mentioned there, I have the same problem in Utopic AMD64 with MATE 1.8.1; this began immediately on my upgrade from Trusty to Utopic and continues to the present. I have a double mouse pointer appear intermittently during web browsing (Firefos 35.0.1), often when click-dragging a link to open in new tab, and then it persists. Although two pointers are visible only the left pointer is active. If I log out and back in, the single mouse pointer is restored.

This is a Lenovo IdeaPad Y510P with the latest BIOS, and I am fully updated on Utopic AMD64 with no broken packages etc.

Status changed to 'Confirmed' because the bug affects multiple users.

Jens Herrmann, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1414778

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.

This is strange, I remember having answered this weeks ago and had also received a reply of yours. I was not able to reproduce the bug in 15.04. and you wrote this would likely not be fixed in 14.10. except I manage to convince the developers of its importance.

[penalvch (penalvch)]

Jens Herrmann, regarding this bug report, no such conversation occurred. Are you referring to another bug report? If so, which on precisely?

[Launchpad Janitor (janitor)]

[Expired for xorg (Ubuntu) because there has been no activity for 60 days.]

[penalvch (penalvch)]

Jens Herrmann, following up on https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1414778/comments/7 , given this issue is not reproducible in 15.04, would you need a backport to a release prior to Vivid, or may this be closed as Status Invalid?

[Jens Herrmann (bugs-u)]

I am still not able to reproduce this. As far as I am concerned this bug can be closed.

[penalvch (penalvch)]
