When I open the attached try1.html file inside a QWebView widget, I do not see anything at all. Strangely enough if I remove the "<style>...</style>" tags from the HTML page, I do get the correct rendering. In fact, the rendering is OK as long as there is no "border-*" attributes in the style section. Reproduction steps: 1. Save the snippets below as try1.html and try1.svg in some directory 2. Open designer and drag/drop a new QWebView to it. 3. Make the Url point to file://where/ever/you/downloaded/try1.html 4. Preview Now notice that there is nothing displayed in the window. Now comment out all the border-* attributes. You will now see a set of radial gray lines. This is expected. I of-course do not see this problem in a recent version of chrome. I used the latest PyQt (which uses Qt 4.7.1) to see this problem. (I am not sure if the version 420+ is correct. I took a guess)
Created attachment 85755 [details] HTML page which shows the bug
Created attachment 85756 [details] SVG file to go with try1.html
The test case works for me on trunk. This is probably an old bug that had already been fixed upstream.
