Hi Sig, I'm off away today so can't spend much time on it but I
installed it on a fresh squeak-dev image (sq3.9-7067dev07.08.1.zip).
Here my spec's...

WinXP Home SP2
Mobile AMD64 3000+
ATI MOBILITY RADEON X700 x86/MMX/3DNow!/SSE2 (64Meg)
OpenGL 2.0.6590 WinXP Release
glinfo-report.htm

Yes i disabled updating while draggin, because it requires an overlay
support (which is not done yet).
I plan to implement a caching canvas which will work by using FBO.
Morph carried by hand (when you dragging it) is rendered on cached
surface and then is  drawn as overlay on main surface.

Yes, there are many issues with morphs. Mainly because they written in
style assuming that they drawn by software blitter. I didn't tested
much of morphs, just basics by now.
In my image baloon text rendered as garbage too. :)
There are issues with font rendering and bitmap formats used by
squeak, which need to be translated before GL can use them as
textures/bitmaps , like byte order in word, bit order in byte e.t.c.

If fonts corrupted, you can use  Display getCanvas flushCache. It can
help, because it frees all cached glyphs and reloads textures for all
used fonts again.

Good start!
