New issue 215 by atdi...@gmail.com: Visual artifacts noticed in
ActivityExample, Position Path Activity Example
Noticed in 1.3 and during testing for 1.3.1-rc, on Mac OS X.
The animations leave behind lines that don't erase. In the latter example,
it took a little while to show and zooming seem to exacerbate it.
Not intending a fix for 1.3.1, but future.
