Mesh: Memory Leak

[ave4]

In the case of rendering animation with a mesh, there is a very fast memory leak. As a result, if rendering is not stopped, the computer will simply freeze from a lack of RAM.
At the same time, the animation without mesh is rendered normally.

I brought this problem under linux. Under windows and OSX I can not check. So users of windows and OSX write, do you have this problem.

Thanks for the report @ave4
Pending validation by others on Linux and confirmation on Mac and PC this looks to be related to previously reported issues with plastic mesh.

I did some research. Where I checked OpenToonz behavior under Windows 8.1

1. A memory leak occurs under Windows, when I rendered my test scene, I also had a RAM shortage error. Also, if it is useful, unlike Linux in Windows, after a few seconds, the consumption of RAM immediately reaches 80-90% and then very slowly. At the same time, the consumption of Linux RAM grows slowly and evenly until an error occurs.

2. In Windows, after stopping (completing) the render, the memory is released. At the same time in Linux, the consumption of RAM does not decrease even after the completion of the render.

A pending fix in Tahoma2D might address this issue.
