What you did
cargo run --release --example many_cubes
I went to have a meal and when I came back, I discovered that the memory usage had increased significantly.
after profiling , I identified a memory leak of approximately 100 KB/s (at 400 fps).
The memory leak appears to be positively correlated with frame rate.
This issue can also be reproduced in the 3d_scene , resulting in a faster leak (500KB/s 1600fps) if you enable AutoNoVsync.
