ArcGIS js API 4.x : Is there memory leak when adding and removing graphics in the view

Question

Hi,

here is a little sample with a button which remove graphics and add 5000 new random graphics to the default graphiclayer .

we can see that the memory increase after each click and is never released even if we force garbage collection in the browser.

May be there is a mistake in my sample?

Is there a memory leak in the API?

Is there a workaround to adda and remove graphics periodically without memomry leak?

Browser used : Firefox (60.7.2ESR)
ArcGIS API for JavaScript : 4.11

Thanks in advance

Robert,

I tested with Chrome 75 and reproduce that issue.

GC occurs but not all the memory is released.

After several add/remove of graphics, the memory increase ever and ever despite of the GC.

Thanks for your help.

I sorry I forgot the part about you using Firefox. I tested in Chrome and did not have that issue.
