It depends on the photographer, the image, and the kind of correction. In my case using a smaller brush size would leave brush patterns on areas of the image with a smooth pattern (like the sky or water). The larger the image, the more likely you'll need "large" brush sizes. My images are 12.8 megapixels.
Furthermore, the size I used on the test, 1000 pix, is not by far the largest I normally use. So to answer your question, YES very common.
I was really hoping this was not a bug, but related to my graphics card. However, since it is, I'd advice you to raise the severity.
