Bug 106672 – [Texmap][GTK] The poster-circle doesn't appear.

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[ChangSeok Oh]

The poster-circle animation isn't shown before resizing the window.
Visit http://www.webkit.org/blog-files/3d-transforms/poster-circle.html
I checked this issue is still there to WebKit 1, 2 using texturemapper AC for gtk port.

Which existing test covers it?
I think we should add a new test for this or the regression would come back.

Yeah.. I didn't realize there wasn't a proper test for this bug since current gtk port has disabled compositing tests..
Let me include a pixel test for this.

Maybe false alarm? It seems related with system environment setup.. :( 
Or is there any special way to include png files?

I don't understand what this test does, and how it relates to the DrawsContent flag.

If you run the attached test, you can see nothing drawn on webkit with texturemapper.
The rotating blue rectangle should be drawn on a separated GraphicsLayer since it has an animation property. Even though a GraphicsLayer is created for it and layer tree is structured successfully, the layer doesn't appear on screen. Because it doesn't have a change to call setNeedsDisplay for the layer. For these reason, we should call setNeedsDisplay for the layer(having animation) in proper somewhere.
As my investigation. mac port and gtk port with clutter ac work fine for this test. because I think they are call setNeedsDisplay when the drawContent value is changed.

The test verifies that the layer (rotating blue rectangle in the test case)  is actually drawn on window by comparing with the expected png result.

Please add parantheses,
if ((changeMask & DrawsContentChange) && graphicsLayer->drawsContent())
