Bug 267645

Happens for me too, works perfectly with QGraphicsWebView test code tho.

I cannot duplicate this with konqueror + kwebkitpart. Howeverm my QtWebKit version the latest trunk ; so that might be why. I am sure you both are using QtWebKit that came with Qt 4.7 which is a rather old version of QtWebKit, v2.0.

Anyhow, can anyone of you test this with the arora webbrowser to see if you can duplicate the problem with it ? If you can, then the issue is upstream and something that has already been fixed because it works fine for me here with QtWebKit trunk.

Tried hard. No, i cant replicate this with arora.

Qt 4.7.2

> Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/533.3 (KHTML, like Gecko) konqueror/4.6.41 Safari/533.3

> Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/533.3 (KHTML, like Gecko) rekonq Safari/533.3

Does not work.

> Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/533.3 (KHTML, like Gecko) Arora/0.11.0 Safari/533.3

Works.

Do not know if this helps.

QtWebKit that came with Qt 4.7 which is a rather old version of QtWebKit, v2.0.

How can i check it?

I can install qt-git, but

http://qt.gitorious.org/qt/qt/blobs/master/src/3rdparty/webkit/VERSION
http://qt.gitorious.org/qt/qt/blobs/v4.7.2/src/3rdparty/webkit/VERSION

show the same version for me.

Yes, looks like qtwebkit 2.0 to me. But i am not sure that is the source.
Arora works for me.

Yes, the QtWebKit version included in Qt is the same old version. QtWebKit 2.0. In order to get more recent versions of QtWebKit, you have unfortunately clone the qtwebkit git and compile it. See the links below on how to do that if you are so included

Hmm... It is weird that Arora renders the page fine for you. I just do not see on my machine with either konqueror + kwebkit or reKonq. The green Top is at the top of the page and Bottom is at the bottom.

Let me ask you to try something. If you have caching enabled, can you disable it and clear the cache out and try it and see if the problem goes away ? Quick way to do this is:

- Press ALT+F2
- Type 'cache' and press enter
- If "Use Cache" is checked, click on "Clear Cache" and uncheck "Use Cache"

1) Cleared the cache, turned it off.
2) Tried to open the page in konqueror or rekonq, did not help.
3) Konqueror and rekonq — the bug is present. Arora — everything is ok.
4) ~/.kde4/cache-pc/http/ contains one file, scoreboard.
5) Turned the cache back on.

I compiled QtWebKit 2.1.x.

> Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.3 (KHTML, like Gecko) rekonq Safari/534.3

I can not reproduce this bug in rekonq using „LD_PRELOAD=./WebKitBuild/Release/lib/libQtWebKit.so rekonq“.

But why is kdewebkit+qtwebkit 2.0 broken, when arora+qtwebkit 2.0 and kdewebkit+qtwebkit 2.1.x not?

I compiled QtWebKit 2.1.x.

No idea. Perhaps the font settings used in the KDE does not gel well with QtWebKit's and one of the many many changes in 2.1.x fixed the issue ? Anyhow, I personally suggest that you stick with the 2.1 version since it contains a huge number of important fixes. [1]

Anyhow, I am going to close this as an upstream issue that has already been fixed since there is nothing we (read: KDE) can do about rendering related problems in QtWebKit. 

Thanks for the report and all the testing.
