Comment #12 on issue 390604 by
sev...@gmail.com: iframe content disappears
I develop a web based ERP application for my company and it uses iframes
extensively. 75% of my users use Chrome, and once they upgraded to 38 I
started get bug requests like crazy about this. Almost all of the users are
on Windows 7 or Windows 8. I have noticed that this issue seems to only
appear for nested iframes (never occurs on top level iframe, instead occurs
on an iframe loaded in page that is already loaded in an iframe) and it
appears to have some correlation with the browser being zoomed to a
non-default level or a screen with a low DPI.
I can't reproduce it on my development monitors which have an extremely
high DPI. Instead, I will often get a bug that makes the iframe hidden
(which is the bug) but it then displays after about a second (which I
suspect is when the page in the iframe is finished loading).
