confirming

the banner at the top refreshes every 0.032 seconds, causing this behaviour.

both IE and Opera don't do this

wasn't able to find a dupe (not with textbanner, did find one about fast ani
gifs causing it = same behaviour)

->NEW
->BROWSER

1)  Leaving bugs assigned to the old component owner when changing components is
    bad.  Don't do it.
2)  This worksforme in a current trunk build (though not in one two weeks old). 
    Probably fixed by the bug 238493 checkin.
3)  Please don't mark layout bugs as NEW without a minimal testcase.

Reassigning to confirmer to produce such a testcase.

Which bug number was this?

Comment 3

[Peter van der Woude [:Peter6]]

A. sorry for setting the worng component, I thought General was right
B. No, this is not fixed on Firefox Trunk (tested latest build)

reproduce:
1.open http://free.grisoft.com/freeweb.php/doc/2/
2.put your cursor in the input at the top of the page
3.type a few letter
--result: an erratically blinking cursor/caret
4.disable the only script on that page
   <script src="http://free.grisoft.com/v5/css/marquee.js"
type="text/javascript"></script>
 (disable javascript or use adblock)
5.reload the page
6.put your cursor in the input at the top of the page
7.type a few letter
--result: an normal blinking cursor/caret

Comment 4

[Peter van der Woude [:Peter6]]

btw, this has nothing to do with gifs
I just saw the same caret behaviour described in an old bug with an ani gif.

the scripts refreshrate of 0.032 secs is the problem

var DELAY = 32; <---------
var STEP = 1;

var currL = 0;
var sprite;
var spriteWidth;
var frameWidth;

function initMarq() 
{
	frameWidth = parseInt( document.getElementById("tpthmarq").offsetWidth );
	sprite = document.getElementById("tpthmarqins");
	spriteWidth = parseInt( sprite.offsetWidth + 20 );
//	if( spriteWidth < frameWidth )
//		return;
	currL = frameWidth;
	scrollMarq();
}

function scrollMarq() 
{
	sprite.style.left = currL + "px";
	currL = currL - STEP;
	if ( currL + spriteWidth < 0 ) 
		currL = frameWidth;
	window.setTimeout( "scrollMarq();" , DELAY );
}

Not wrong component.  Wrong assignee.

> 3.type a few letter

That's not the bug reported in comment 0.  That's a different bug.  Please don't
hijack bugs.

Comment 6

[Peter van der Woude [:Peter6]]

I never assigned anyone for it Boris.
Just changed 
Firefox->Browser
Unco->New
General->Bowser General
Never touched anything else

[Boris Zbarsky [:bzbarsky]]

That's the point.  When you change components, you need to check the " Reassign
bug to owner and QA contact of selected component" checkbox.  Otherwise it's
left assigned to the wrong person.
