Status: RESOLVED WORKSFORME

(Core :: Widget: Win32, defect)

Build ID: 20121211030855

Steps to reproduce:

A slower network connection will help to see multiple repaints.(though its not necessary at all)

1. Create a new profile
2. Disable HWA
2.5 Enable debug paint flashing
3. Open three tabs that are heavy, i.e use lots of images and some social network. Eg.   http://www.extremetech.com/
http://www.tweaktown.com/
http://vr-zone.com/

4.Open a new tab. Go to it.
5.Right click on a tab and select "reload all".  



Actual results:

While the three heavy tabs are reloading, the active tab will undergo multiple full screen repaints.


Expected results:

Background tab reloading should not have affected the current tab. 

The three sites i listed have a auto-reload function. So when they auto-reload, you can see the current tab repainting.

Is this a regression?

I couldn't reproduce this issue with the steps in comment 0. The active tab only got repainted once per reload selection.

> Is this a regression?

Appears to be. I cant reproduce this on FF15.
Slightly different STR :

1. Create a fresh profile. Disable HWA. Restart Nightly.
2. Enable debug paint flash
3. Come to this page.
4. Quickly, ctrl+tab these three sites :   http://www.extremetech.com/    http://www.tweaktown.com/    http://vr-zone.com/

5. As the pages load and their layout is reflowed, the current tab(and the tab strip) will repaint.

Would a Screer help ?

There are to WORKAROUNDs:

#1 If I set |display:none| to .statuspanel-label then the problem does happen.

.statuspanel-label
{
display:none;
}

#2 Disable Flash plugin

The user impact here is not enough to track for release.
