Navneet the default in step-44 is to use quadratic elements, and the call to DataOut::build_patches() then outputs each cell as a collection of 2x2 quadrilaterals. In cases such as this, you get artifacts like the ones described here: https://github.com/dealii/dealii/wiki/Frequently-Asked-Questions#in-my-graphical-output-the-solution-appears-discontinuous-at-hanging-nodes So yes, what you are seeing your output is an artifact of visualization. These artifacts become smaller if you refine the mesh more often.
