Test app to reproduce the issue. Sources and Symbian .sis package.
Could you please test a trunk build? It may not be specific to 2.1. Regarding versioning, we don't track QtWebKit versions on bugzilla. We keep bugs open for trunk and add them to meta-bugs if they are fixed on trunk but affect a stable release. If we confirm this bug doesn't affect trunk, it should be closed as FIXED and added as a blocker to bug 59935. (In reply to comment #3) > Could you please test a trunk build? It may not be specific to 2.1. I'll try to build QtWebKit for Symbian from trunk, but somehow have the suspicion that I will fail at that :) Anyways, I remember having had a device with Symbian "Master code line" in my hand, with a QtWebKit version installed which did anti aliased canvas drawing. Perhaps there was a QtWebKit version 2.1+ installed. Since QtWebKit is "built-in" I unfortunately had no chance to find out the Qt/QtwebKit versions. I bricked that phone (N8 prototype) in the meantime. I set (very) low priority for now. I have the feeling we have bigger issues than that on Symbian and we should not focus too much on that platform anyway. Alessandro, if you know about a critical use case that would justify a higher priority, please comment. @Benjamin: I am fine with the priority. This was just intended to document the issue. And considering that it was me (I am not a web guy) who found this issue, it seems that no developer really uses HTML5 in QtWebKit on Symbian :) Unfortunately, this issue is a regression. The rendering on canvas is beautifully anti aliased when using the QtWebKit version that is in the Qt/4.7 repo (Must be an ancient version). So, QtWebkit 2.1 has that issue and probably also later versions. Rev78332 (bug 51169) might have solved this issue. Are you in a position to retest (you could perhaps download a sis file from the build bot - http://build.webkit.sed.hu/buildslaves/szeged-symbian-1) ? Thanks. This is a regression from QtWebKit-2.0 (qt-4.7), so I'm marking it as a blocker. Laszlo said it may have been fixed in r78332 (bug 51169), need to check. I emailed Alessandro and he replied unsuccessful to retest due to some certificate issue. I propose this removed from blocking 55055 (In reply to comment #10) > I emailed Alessandro and he replied unsuccessful to retest due to some certificate issue. > > I propose this removed from blocking 55055 Could someone with a 2.2 build of Symbian run the smal test case. So we know if the bug still exists? that the rendering is fine now, and nicely antialiased http://bscmswww.americas.nokia.com:58080/document_browser/ccm_wa/bshud001/ASF-ido-armv5-release/builds/97/archive - not reproducible. Closing as works-for-me then. Please reopen if someone reproduces it somehow. |
