When the plugin is in an iframe that is offset, the rendering of the plugin is incorrect. Please see attachment.
Also note that scrolling the iframe will cause render issues with the flash plugin as well.
This also affects the silverlight plugin and most likely any other plugin.
Tested using the Qt 4.8.0 RC1.

This does not affect Chrome, only the new Qt Webkit in Qt 4.8.0 RC1
I am seeing the same thing in Qt versions 4.8.0, 4.8.1, 4.8.2. This is preventing me from updating from 4.7.5.
I have web view with an iframe in the lower-left corner, 300x250px. When the frame loads, a white box flashes in the upper left of the window (as if the iframe were located at the top-left), and the actual iframe never renders anything.
Reproduced same issue. Qt 4.8.1
