<pre>This happens in ephy at startup when restoring tabs from a previous session. Tabs that are loaded in the background, are fully white when visited the first time, until a redrawn is forced, for example, moving the mouse over the view, or resizing the window. It doesn't always happen, so it looks like a sync issue between web and ui processes. When using the threaded compositor it happens more often. When AC is not forced to be always enabled, it never happens. It happens with 2.12 branch too, so it's not a recent regression, I think it has always happened.</pre>
