I have never noticed any slowness in this area. I tend to use very
few add-on features when I configure the image. Just for purposes
of narrowing down the issue, maybe you could try running a fresh image
with no fancy preferenced enabled, just to see if the behavior changes.

I use a Linux PC with various VMs and images, including the latest Squeak
trunk, and I do not notice the symptoms that your are seeing.

I hope your "little demo" went well :-)

> FWIW, I do recall discovering, and submitting a fix for, another issue similar to this sometime in the last 2-3 years ??? something about the extent (?) of text-related morph extended far beyond the bottom of the area containing it (?) but that is all a distant memory to me now.  My change was discussed on the list, but I don't recall if it was accepted into trunk (I think it was) and of course have no idea whether it was cherrypicked for release (if that's something that happens).
