We have a problem with colored TT font rendering. In your test
project, if you remove the drop shadow in your example, memory
consumption stays sane. My guess is that with a drop shadow,
rendering switches between black and blue constantly, thrashing the
TT glyph cache.
Btw, your games are beautiful! Switching projects is quite slow on
the XO (up to 20 secs), not sure why that is. But it looks great and
once in the game it is fast enough. Sound did not work on my joyride
build (fine on the Mac). And the purple UI is somewhat dark in
reflective screen mode because of the way the DCON maps colors to
A quick way of testing it on an XO is putting your image onto a USB
Flash drive in a folder named "olpc-dev", and rename it to
"etoys.image". Then clicking the Etoys icon will use that alternate
image (we put that in for debugging).
If you can make an SVG activity icon I can help you create a
proper .xo activity bundle from it (unless you have that already).
And did you think about Journal integration and sharing, yet?
