Status: RESOLVED WORKSFORME

(Core :: Graphics: ImageLib, defect)

Description

[spoke]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121129183639

Steps to reproduce:

With javascript I refresh a picture every seconds :

<img src='s3d3.synI.php' name='Image1' id='IdImage1'>
.
.
function DispImage()
{
  document.getElementById("IdImage1").src = d.src;
  d.src="s3d3.synI.php?tst="+Cpt++;
  setTimeout("DispImage()", 5000);
}




Actual results:

During the refresh of the picture, it first blank it and after it draw it. So you can see a blink evry second.
I have try on many different machine it's the same. If I use older version of firefox it's ok.


Expected results:

It sould show picture directly, without blinking.

On this link you can see an example :

If you try it with an old version or on chrome for example you will see the difference.

FWIW, seems to be OS-specific since testing on Win7 x64 this is WFM against 17, 18 and Trunk (HWA on/off).

Can you get a Regression Range against Central Repo?

I'm confused:
http://www.elliochris.fr/s3d3.synH.php leads to a different Site as can be seen on the Videos?!

Sorry, It's because I have an hundred of pages that have the same problem. All with this kind of script :

<img src='s3d3.synI.php' name='Image1' id='IdImage1'>
.
.
function DispImage()
{
  document.getElementById("IdImage1").src = d.src;
  d.src="s3d3.synI.php?tst="+Cpt++;
  setTimeout("DispImage()", 5000);
}

Only the img src are different.
