Bug 142532 – [GTK] Contents not correctly laid out when the web view is not realized

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

This can be easily reproduced with epiphany:

1- Go to google, and search for something you know will give a youtube link
2- Middle click the youtube link to open a new tab
3- Visit the tab

After 3, sometimes the layout of youtube is like if the web view were a lot smaller (like the mobile layout, using a single column).
I'm not sure the problem is related to the accelerated compositing mode, I've managed to reproduce the issue disabling AC, it didn't happen that often, but I could still reproduce the problem. So, maybe this is more related with the delayed resize we do when the web view hasn't been mapped yet.

Do we have a guarantee that webkitWebViewBaseGetPage never returns null? (If so, perhaps in the future it should return a reference rather than a pointer.)

So far I've found this has fixed:

* YouTube video pages
* Images in Vox articles
* Layout and images in CNN articles

And no doubt many more. Also, it made anchor links work.
