Sluggish cursor movement when firefox is running for several hours.

[Vish]

Binary package hint: firefox-3.5

In Karmic , when firefox is running for *several hours* the cursor movement becomes sluggish.
as in > when the cursor is moved with the arrow keys pressed [key press repeat enabled]
- the cursor stops , as if the cursor got stuck because firefox is not responding , and then appears at the new location.
- when actually it is just not displayed during the movement.

This does not happen when firefox is started fresh. it only happens when firefox has been running for several hours [in my case i keep firefox running always and only close it when i notice such behavior.]

This is a regression and did not occur with firefox 3.0

This may be related to Bug #413950 and the upstream bug > https://bugzilla.mozilla.org/show_bug.cgi?id=511955

Or to the firefox behavior of hogging memory , but this did not happen in previous versions where even when memory usage increased,over long hours of use, the cursor did not show such behavior.

I think this bug has been solved. I'v not noticed this behavior for a couple of weeks or maybe even longer...

I am currently encountering this bug, and it occurs all the time that I run Firefox (not just after several hours). I updated Karmic Beta late on October 6.

Whenever my cursor is in a text field or the URL bar, if I hold an arrow key down, the cursor will move once, then freeze while the key repeat kicks in, and then when I let go it will abruptly leap to its destination (which corresponds to how long I held down the key).

From my experimentation, I find that this doesn't happen for other keys that repeat, such as letter keys or backspace. It doesn't happen when I use arrow keys for something else, such as moving the page. It doesn't happen in other applications I've tried besides Firefox, but it *does* happen in both firefox-3.5 and firefox-3.0.

So this was always an issue for you and not a regression?
