That is an issue that has existed for a long time, Gimp uses the screen coordinates to paint. So zoom out, and get crappy lines, no curvy smoothing or anything. Only way to get non polygonal lines is to zoom in, which severely limits what you can paint in a single stroke and gets in the middle of workflows that rely in constant global view and work area, obviously. Anybody can test, with mouse too, a 512*512 image will be enough. Set zoom to 4:1 and paint a rough circle with Paintbrush and Circle 01 brush (100 or so pixels of diameter, look at the guides before starting), then set zoom to 1:4 and paint a similar circle next to it (paint, not select and stroke). Compare how zoomed in gives a smooth line and zoomed out gives seems to be based about jumps of 4 pixels. I am unable to find the bug about this, I think there is one, I managed to find lots about the display side of the problem, but not checked all of them to see if the input issue is there (I am sure the issue about input has been raised enough times that people would remember it... seems not due the other replies, always pointing to "not using Pencil?" or "blur your paint"). One of such references to the issue is in last line of comment #1 of http://bugzilla.gnome.org/show_bug.cgi?id=134410 May I suggest you fill a bug? If someone else finds the original, yours will be closed as duplicate and all happy. And if I remember wrongly, well, now there will be such bug.
