Sorry about being so vague -
I'm using Task Manager to monitor memory usage, I'm aware of the
innacuracies but from what I've seen from monitoring previous
applications (pygame/opengl), the current behaviour seems very
unusual.
The memory usage increases when resize is called and it appears a
little more when draw is called (but only the first time either of
these are called for each object), and stays the same when the Layout
object is deleted - that is, never goes down at all. If I create a
Layout object once and it uses 50KB, for example, then if I create the
same one and delete it in a loop 100 times, task manager indicates
that all 5,000KB of memory is still in use. This doesn't appear to be
released at any point no matter how long I run an application for.
