Previously instances of the IText shape were added to a globally-shared array when they were created. There are two problems with this approach: 1) Interactions with one canvas affect others. I would never expect text in one canvas to exit edit mode just because I interacted with some otherwise-unrelated canvas. 2) Every IText instance leaks. There is no mechanism to clean up references to IText instances in the global array, so every such instance will hang around in memory forever, regardless of whether it is removed from the canvas or if the canvas itself is removed. Discovered while profiling memory usage in Chrome. |
