Bug 44367 – [Qt] Accelerated Compositing is off by default even ACCELERATED_COMPOSITING flag is set

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKit Misc.

[Dan]

Qt Webkit port of trunk r64996
running test cases using "WebKitTools\scripts\run-launcher" on Windows
QWebPageClient's implementation of allowsAcceleratedCompositing returns false even though ACCELERATED_COMPOSITING flag is defined.
The result is RenderLayerCompositor is not creating RenderLayerBacking for the layer with transition or animation style set.

Ok, the reason for QtTestBrowser not to use accelerated composition is that it has to run with "-graphicsbased" flag but by default "run-launcher" does not specify it even when compiled with ACCELERATED_COMPOSITING flag. So the issue is rather with QtTestBrowser or lack of documentation on accelerated composition.
QtTestBrowser could change this pure run-time verification
    if (args.contains("-graphicsbased"))
        windowOptions.useGraphicsView = true;
to be based on compile time flag ACCELERATED_COMPOSITING.
Thanks.

Closing as invalid, just a missunderstanding about accelerated compositing.
