Unmanaged memory leak

[JerryGray12]

My company is using LottieSharp to display JSON videos in our application via the WPF LottieAnimationView. We are just setting a file name and setting AutoPlay=true. When I run a test program that just displays the video second window, the Unmanaged memory goes up by 8 MB each time the video is run.

We do automation testing on our application and since we have added LottieSharp videos, the automation testing fails quickly with out of memory exceptions.

The leaks appear to be in the SharpDX library.

Is anyone else seeing these?

Expected behavior No unmanaged memory leaks.

Desktop (please complete the following information):

• OS: Windows 10 64-bit
• Browser [e.g. chrome, safari]
• Version Nuget package 1.1.1 for windows desktop development

I try to solve this bug but it is related to SharpDX is not terminating objects. So still under develop

[rasgath]

I want to kindly ask, if there is already an update on this? UserControls containing LottieAnimationView are not removed by garbage collection on UserControl Disposal.

@rasgath Yes. if you check in develop branch you could see I trying to solve this problem. But I can see there is a memory leak in SharpDX which is depricated. So what I doing now to finalized some known bug and then working on a new version that using SkiaSharp. But for the moment I have no idea what could be the best graphic engine backend. SkiaSharp or other alternative to SharpDx.

As I mentioned many times. this is the only WPF Lottie viewer and we need help from comunity to solve the bugs.
