Rendering issue in QStaticText

When QStaticText is used with QPainter::OpenGL2 as paint engine, it does a wrong rendering of the glyphs when large fonts are used: The glyphs are aligned wrong horizontally and get partly clipped.

Attached is a Qt-only application that shows the problem. The application draws the same text on the same position once with QPainter::drawText() and with QPainter::drawStaticText(). If the application is started with -graphicssystem x11, the rendering of the text is absolutely identical. If -graphicssystem opengl2 is used, the glyphs are aligned different for QPainter::drawStaticText() and partly clipped.

The issue seems only to occur for quite large font sizes.
