Windows 7 Professional, 64 bit OS. Qt 4.8.2, potentially already in 4.8.x (worked with 4.7.x)
Description
On Windows 7 (works on OSX, other platforms not tested):
Rendering fonts using overpainting results in unwanted, randomly dotted underlined text, when the subclass of QGLWidget is created with a QGLFormat that has the QGL::AlphaChannel flag set.
It can be reproduced by adding the QGL::AlphaChannel flag in the Overpainting example (http://qt-project.org/doc/qt-4.8/opengl-overpainting.html).
