Bug 39297 – WebView doesn't repaint until page reloads when page using hardware acceleration loads just after waking from sleep

• Status: RESOLVED
• Resolution: FIXED
• Component: Layout and Rendering

[Adam Roben (:aroben)]

To reproduce:

1. In a build with the fix for bug 39295, go to <https://bugs.webkit.org/attachment.cgi?id=56382> (which reloads itself every 5 seconds)
2. Put the computer to sleep
3. Wake the computer up

The WebView doesn't repaint until the page reloads itself.

The problem is that calling Direct3DCreate9() shortly after waking from sleep returns an IDirect3D9 for which IDirect3D9::CreateDevice will always fail. We need to detect this and throw away the bad IDirect3D9 and ask for a new one.

Typo, "on-bad"

Whoops, that was supposed to be "non-bad". Will fix.

Thanks for the review!
