[Bug 1025013] Re: Resize scratch window, it doesn't update, goes black, and shrinks to a vertical strip in Unity-3D.

[Amos Blanton]

I've made an edit to the debian scratch repository, here:

https://alioth.debian.org/projects/pkg-squeak/

After some testing, they should submit an update containing this and
other fixes soon.
