How to clear the memory occupied by the browser？

[abluobo]

I'm using the latest version of Cornerstone 3D for a project and I have a viewer component that uses it, I'm trying to clear memory when I unmount the component, here's the beforeDestroy function I use:

beforeDestroy() {
    cornerstoneTools.destroy()
    RenderingEngine.destroy()
    this.renderingEngine.destroy()
  },

However, there are still a large number of memory leaks, even if this function is run when the component is unloaded

Is it wrong to use the way of clearing memory? How to clear memory in the right way？

maybe clear the cache as well? cornerstone.cache.purge

I used the purgeCache() method, but it didn't work

Viewed through the task manager, the memory occupied by Google Browser has not decreased significantly after uninstalling the interface components

Can you do a memory profiling and send the results here? I recorded myself in the past for how to profile (maybe you already know it)

I made a memory profiling with reference to the operation process of the video, and the following is the results

Can you please help me debug this?
See here, can you make the same recording starting from before load, load, clean up, along with all the memory graphs.

Thanks!

In my project, the prefix of imageId is 'wadouri:' rather than 'streaming-wadors:' or 'wadors:', This is where I can think of different places.

So update:
This is a issue for Intel integrated graphic cards and does not relate to our libraries (seems like)
Can you make sure your driver is up to date (31.xxxx)
