Right, the rest of the buttons are rounded in a way that doesn't respect the theme. It's another example of where a global roundness setting would be helpful. In the meantime, we should probably just be consistent with Breeze's default corner radius.
This is fixed in Plasma 6.1 with the new unified global corner radius value!
