Hello, I’ve been trying to implement a perlin noise editor (github.com/fnadalt/mundo/perlingen), using panda3d 1.10. There’s a main menu that has a button to open the tool. When I close the tool the memory seems not to be freed. As I reopen/close the tool, memory use increases (PStatsClient/SystemMemory). MemoryUsage shows GeomNodes increase. I tried to be carefull with cyclic refs, so I implemented a kind of twisted system to avoid it. I used DirectGui .destroy() method. Please take a look. Thanks
