I have a Qt application misbehaving on macOS. The UI is garbled in various ways. As part of diagnosing this I would like to hit a hot key and bring up a HUD to interactively browse Qt's internal resources it uses to render itself, such as OpenGL textures and other surfaces to see what it has cached.
Does it have such a feature?
KDAB's GammaRay is what you are looking for.
