Nothing small, but if you're prepared to do build something more
Build from the "local_customisation_no_pours" branch.
(With stgit I'm lazy about making "proper" feature branches ;)). Note
that I rebase this branch a lot, as it is from a stgit series.
I'll send you the PCB layout I've been testing it with privately.
Steps to reproduce are:
1. Load the board.
2. Drag the white / black (depends on your theme) circular control on
the left hand bar. This is a track-ball.
3. Drag like crazy, perhaps stop for a little bit. Drag again.
Eventually it hangs when the full GTT is in use.
