Animation flickering during OS install 12.04

[Neven Blazic]

In the Ubuntu installer, there is a flickering whenever new tweets appear. Video screencast highlighting the problem can be seen in the link.

Thank you for reporting this bug to make Ubuntu better. Marking confirmed.

I did not record other part, but slider animation is also flickering.

I was discussing this with someone yesterday, and I suspect it might be an interaction between Webkit and the graphics system. Are you using Intel graphics hardware?

Have you noticed any other behaviour like this, anywhere? (Especially in the help browser or in browsers using native WebkitGtk, like Epiphany or Midori).

While the slideshow can work around this, it's unlikely a bug in the slideshow: all it does is change the opacity of elements, which Webkit then draws.

I did install both browsers you suggest and did not notice flickering, maybe if there is some url where i can confirm for sure that is working fine.
I have laptop Asus N61jv hd3000 and gf 325.

Okay, one thing to try is over here:

That's the same slideshow being embedded in the installer.

Tested in both browsers and working fine, i did install few times 12.04 because of some other issues and i can confirm its flickering every time, not sure if its important but its same on 32 and 64 bit version.

This occurred to me to, on three machines. Two of them running Intel graphics (GMA4500HD and HD2000) and one running nVidia graphics (9800GTX+).

I'm not currently on one of those machines so I can't test if the slideshow still flickers but I haven't noticed any similar issue when running Ubuntu after the install.

Also i can say it was flickering during installation after disk is formated (clean), later i did try ubuntu live from cd and try that animation link and it was working fine.
