testcase
I tried it on linux with the QtTestBrowser of WebKit trunk with qt-4.6.2, flash 10.0.22.87. The cpu load was normal (between about 10-35%). I would ask you to run your test case against the trunk.

Running the testcase with WebKit r60645 + Qt 4.6.1 (built with VS2008) on Windows Server 2003 shows the same behavior where CPU load spikes when I move the mouse cursor on the Flash swf. I guess something is wrong about window message processing on Windows while it's OK on Linux. Still happening on the QtTestBrowser.exe with WebKit r61615 + Qt 4.6.3 (built with VS2008) + Flash 10.1.53.64 + Windows XP SP3. Can someone on Windows confirm this? A test case is available. Please someone try to confirm it on Windows |
