Qt Quick comes with a few visualizations that are useful for profiling its rendering performance. While these visualizations are built inside Qt Quick itself, there are a few downsides when using them directly. GammaRay makes them much more accessible and useful; in this video, we are going to show you how.

For a more thorough discussion about optimizing the rendering of Qt Quick applications, check out this talk by Giuseppe at the Qt World Summit 2019: https://www.youtube.com/watch?v=SgDTNB20_3I
