Maemo6, see more QT-3986. 284344 1 vestbo 2010-09-24 06:43:53 -0700 Please provide a reduced testcase 287413 2 hausmann 2010-09-30 00:39:25 -0700 Re-opening, QT-3986 contains a test-case that reproduces the issue. From the investigation of Alexis and me it is not unlikely to be a WebKit bug or a bug in Qt that is triggered by WebKit. For the moment we assume it's a WebKit bug and it's tracked here. Maemo bz 190777 has additional information. I'm also adding this to the 2.1 release blocker, but this bug is a regression in 2.1 that does not happen with 2.0. 287480 3 jarmo.backlund 2010-09-30 04:01:02 -0700 --- Comment #51 from Kinnunen Kimmo (Nokia) <kimmo.t.kinnunen@nokia.com> 2010-09-30 13:45:16 EEST --- If you run the app with mtf '-graphicsystem raster -software' flag, you can see it works as expected on device. On host + mtf, raster is broken anyway.. Passing -software to a mtf app disables the usage of glwidget for graphicsview. -graphicsview raster -software -> ok -software -> not ok -graphicsview raster -> not ok Somehow on GL the paint gets black background. Painting with different webkit bg color + alpha does not work, the black rect glows through the translucent bg. QPalette palette = webView->page()->palette(); palette.setBrush(QPalette::Base, QColor(255,0,0,125)); webView->setPalette(palette); 287528 4 hausmann 2010-09-30 06:52:55 -0700 *** This bug has been marked as a duplicate of bug 45509 *** 290263 5 ademar 2010-10-06 06:50:39 -0700 marked as duplicated and therefore should not block the release
