User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17 Steps to reproduce: When Facebook is zoomed in on Firefox, the rendering of the log in page creates a distorted rendering. I zoomed in at 130% and discovered that the page looked completely off upon refreshing. Zooming back to default and refreshing "fixed" the problem. However, I have a 1920 x 1080 display and need the zoom. This has been a problem since I believe Firefox 17. Actual results: Look at the attached file. Expected results: The rendering should remain consistent.

Also, this ma be related to Gecko. Google Chrome had a similar issue, but with other web pages. The Chromium team confirmed that it was a Webkit issue. Upon updating Webkit accordingly, everything was fixed (for the most part).
Confirmed (with full HD screen too). STR: 1) Open https://www.facebook.com/ 2) Zoom In a few times (Ctrl+ 3 times e.g.) 3) Refresh the page (F5) Result: Facebook logo is cropped at the bottom (see http://i.imgur.com/zx4RVQ7.jpg) and some page elements are moved 4) Back to normal zoom level (Ctrl+0) 5) Refresh the page Result: Facebook logo is rendered normally Regression range: m-c good=2012-09-07 bad=2012-09-08 http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=36427d4b2cf6&tochange=1d4fc0c60063

After landing Bug 564815, Firefox has window.devicePixelRatio. So, I think https://fbstatic-a.akamaihd.net/rsrc.php/v2/yY/r/Fu7Ewuy7Zs7.js should be revised. ... __d("PixelRatio",["Arbiter","Cookie","Run"],function(a,b,c,d,e,f){var g=b('Arbiter'),h=b('Cookie'),i=b('Run'),j='dpr',k,l;function m(){return window.devicePixelRatio||1;}function n(){h.set(j,m());}function o(){h.clear(j);}function p(){var r=m();if(r!==k){n();}else o();}var q={startDetecting:function(r){k=r||1;o();if(l)return;l=[g.subscribe('pre_page_transition',p)];i.onBeforeUnload(p);}};e.exports=q;}); ...

Minor rendering glitches when zooming, uncommon user scenario, likely a TE bug. No need to track for upcoming releases.

It looks good for me, since about a week? ago. I've kept my 125% native zoom, because of the 1080 resolution on my laptop. All looks good on my end.
