When maximising the Firefox window, content is not always resized to fit
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.
Just to note that this problem is still present in version 3.0.1
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) - Ubuntu 16.10 64-bit - GNOME Shell 3.20.4
