This looks extremely generic. Is it the end tag of the <rect> that makes the difference or really the opacity? (In reply to comment #1) > This looks extremely generic. Is it the end tag of the <rect> that makes the difference or really the opacity? No, the ending of the rect isn't responsible for the assertions (that's <rect ... /> also fails). According to the backtrace it comes from the destructor of GraphicsContext: #0 0x00007ffff5425878 in WebCore::GraphicsContext::endTransparencyLayer (this=0x7fffffffba10) at /home/reni/repos/webkit2/Source/WebCore/platform/graphics/GraphicsContext.cpp:356 #1 0x00007ffff57bf629 in WebCore::GraphicsContext::platformDestroy (this=0x7fffffffba10) at /home/reni/repos/webkit2/Source/WebCore/platform/graphics/qt/GraphicsContextQt.cpp:324 #2 0x00007ffff5424b85 in WebCore::GraphicsContext::~GraphicsContext (this=0x7fffffffba10, __in_chrg=<optimized out>) at /home/reni/repos/webkit2/Source/WebCore/platform/graphics/GraphicsContext.cpp:92 #3 0x00007ffff7915a04 in QWebFrameAdapter::renderRelativeCoords (this=0x716d90, painter=0x7fffffffbc20, layers=255, clip=...) at /home/reni/repos/webkit2/Source/WebKit/qt/WebCoreSupport/QWebFrameAdapter.cpp:546 #4 0x00007ffff7ba973a in QWebFrame::render (this=0x710760, painter=0x7fffffffbc20, layer=..., clip=...) at /home/reni/repos/webkit2/Source/WebKit/qt/WidgetApi/qwebframe.cpp:643 #5 0x00007ffff7ba980a in QWebFrame::render (this=0x710760, painter=0x7fffffffbc20, clip=...) at /home/reni/repos/webkit2/Source/WebKit/qt/WidgetApi/qwebframe.cpp:653 This may be Qt-specific: I cannot repro it on CR/Skia ToT. Yeah, for some reason restore() is called more often then save(). I can not repo it either anymore. |
