    This is just an example of the native backend being buggy, I don't get why you are trying to blame the fonts.

    It seems only raster is supported.
    It does say the opengl backend is still there though. Once the opengl backend matures it should be superior to both raster and x11. On my intel machine there's barely any difference between raster and x11 speed-wise, and for many raster is actually faster, if you see a big difference you should probably report a bug.

    Those patches seem to be about the build option. If Qt5 allows switching gfx systems during runtime, then good riddance to build switches.

    The QWidget based stack continues to work as in Qt 4.x, based on QPainter. QPainter does however support less backends than it used to. It is now limited to SW rasterization (Raster backend) for drawing to the screen, pixmaps and images, an OpenGL backend for GL surfaces and a backend for PDF generation and printing. The platform dependent backends using X11 or CoreGraphics are gone.
    It seems only raster is supported.

    Qt5 is screwed up on Linux because it doesn't support native graphics system like Qt4 AFAIK, which will mean 6 times worse performance on my PC.

    Linux support in Qt hasn't been "screwed up", so no that did not happen. Too much FUD posted on this site :/

    Yeah, just what this forum needs is more conspiracy theorists. Qt is developed in the open as open source software by various different parties and you somehow imagine that Nokia could intentionally ruin Qt to please some other company in less than a year without anyone noticing or leaking the information? Zester doesn't sound too smart either... a guy that would rather fork an entire toolkit than create an alternate QPA backend.
