If they do, then are the Qt widgets equally-likely to provoke some of the horrible problems I've seen with the OpenGL in
WxWidgets used in Gnu Radio?The OpenGL "eco-system" seems to break randomly, even for apparently-correct applications, particularly when the DRM is used in the X server, but only on certain hardware. This makes it difficult to predict whether a given Gnu Radio application will at some point fail, when run on hardware whose OpenGL/DRM/whatever-the-heck has bugs.
I started looking at Qt (the GRC instance in particular) to see if I could perhaps avoid the whole flakiness in the OpenGL eco-system, but if Qt in turn uses OpenGL to render certain things, then perhaps that's not a wise thing to do?
