Bug 95732 – [chromium] Dynamically removing preserve-3d from a layer has no effect

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Sami Kyöstilä]

http://trac.webkit.org/changeset/126378 accidentally broke the logic for removing preserve-3d in GraphicsLayerChromium::updateLayerPreserves3D().

D'oh! Thanks for adding the test, but why is it in platform/chromium? This should work anywhere, shouldn't it?

why the setTimeout?

Right, I just put it there because this was a chromium bug. I'll make it a shared test.

It's needed so that we first do a commit cycle with preserve-3d enabled and then another one with it disabled. Otherwise we won't hit bug in question, since there needs to be an existing layer with preserve-3d turned on.

D'oh, looks like I picked up the wrong version of this patch when rebasing which still had the tests in platform/chromium/compositing instead of compositing/. Let's fix that...
