Description

10 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008050806 Minefield/3.0pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008050806 Minefield/3.0pre

VERY occasionally Firefox does not resize its display to match a change in size of the window. The attached image shows an example where the window has just been maximised but the content is still occupying the original, smaller size.

Reproducible: Sometimes

Steps to Reproduce:
1. This occurs very infrequently and I don't think it can be reproduced systematically by any normal use of the browser.
2.
3.
Actual Results:  
Content is not always resized to match a change in size of the window.

Expected Results:  
Content should always be resized to match a change in size of the window.

When it goes wrong, the conditon is persistent - I can switch tabs and return to the window and it is still in this state. I can also scroll the content using the scrollbars and drag the frame border up and down. It behaves as if the window is still of the old size.

I never had this bug before, but been using Nightly lately, I can reproduce when I switch to a bigger screen with Firefox maximized.

- Firefox 52.0a1 (2016-11-10) (64-bit)
