886735 - cursor "sticky", often affecting other windows applications

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Michel de Becdelièvre]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130511120803

Steps to reproduce:

Use Firefox. The behavior appears usually, but not always, after long sessions. The mouse cursor becomes sticky, sticking on links, combos, etc. during moves.

This behavior happens for me on Windows 7 and windows 8, for at least the last 3 or 4 versions of Firefox (currently I'm on FF21), on at least 2 different computers. (and possibly on a co-worker machine, but he had not made the link to FF and has recently switched to chrome).

Disabling all extensions => no luck.



Actual results:

After a while this behavior contaminates windows in it's entirety, with sticky behavior appearing on the file explorer and even on (DirectX ?) games, etc.

Sticky behavior in explorer and other affected applications disappear when Firefox is closed.



Expected results:

Normal, smooth mouse movement.

NOTE : a quick Duck Duck Go search shows a similar experience here, with FF18 on XP :

Hardware/driver issues?

This kind of issues is hard to track, especially when it's not reproducible easily (testing during a few hours is not very reproducible).

Did you observe this issue with previous versions of Firefox?

  As I recall, I had the problem, probably once a month or once every 2 weeks for probably 2 years now. So, yes several versions of Firefox are affected.
  I had so far never made the connection with Firefox, I only thought about it when looking for "jumping cursor" on "duck duck go" and finding references to Firefox. And then closing ff solved my latest batch Of troubles.
  I have a feeling that it occurs more often when my FF sessions has been opened for days, specially on one of those newspaper or news or technical websites with lots of live javascript / flash / whatever.

As a developer, I know how frustrating it is to get this kind of vague report for a bug. Sadly, I have little else to offer.

Would a memory dump of the process help, next time it happens ? Or any other suggestion ? I'm a software engineer, you can go technical.

You could try a new Firefox profile, in case the current one is corrupted:

This might be also caused by a bogus desktop app. You could think of what's running besides Firefox on your computer.

Closing bug due to lack of response by reporter.
