29723 - Things move when objects are given focus

Status: VERIFIED DUPLICATE of bug 7617

(Core :: Layout: Tables, defect, P3)

Description

[Jesse Ruderman]

All problems refer to the default display of http://www.slashdot.org.

- If you press tab a few times, the ad bar will move slightly to the left, and 
the middle column (with the articles) shrinks

- Put the login form (right column) in the middle of your screen by scrolling. 
If you click-drag on one of the links above the login form (in order to start 
tabbing from there), and press tab a few times, the nickname and password boxes 
grow and shrink a tiny bit as you tab onto the links below the boxes.

- If you scroll all the way down, and then click-drag-away on search, you'll 
find yourself scrolled up a notch.

The fact that things move and change size imply that incremental reflow is 
producing a different result than normal reflow.

Assigning to Chris for that problem. There's the bigger issue of why we're doing 
all the reflows, but that is probably covered by existing style bugs

Maybe doing lots of reflows is good for finding discrepancies between normal 
and incremental?

Is there some way to test whether mozilla will draw a page in the same way 
using one normal reflow or a zillion incremental reflows, or is it more 
complicated than that?

Same problematic as in bug 29739, isn't it? Please check and mark if necessery 
as a dupe... (there are a lots of dupes of this symptom around)

No, bug 29739 is a scrollbar regression and had been marked as a dupe of another 
bug. Marking this as NEW. Just let chris take a look at it.
