BurstTriangulator Leak

Hi,

I’m getting the following leak message in the console. I saw this forum talk about something similar, but I wasn’t sure if this fix has been applied yet? Or if my issue is different.

I’m using Unity 2022.3.55
Astar 5.2.5
Entities 1.3.8
Entitities.Graphics 1.4.5
Unity.Collections 2.5.1
Burst 1.8.18
Mathematics 1.3.2

The patch mentioned in the thread hasn’t come out yet it seems- the last update was November 20th, but Aron’s comment wasn’t, funnily enough, until November 21st.

Hi

This is a unity bug. I’d recommend upgrading collections, burst and, if possible, your unity version.

Thanks for the response and info. I have burst and collections upgraded as much as possible in my project (Collections 2.5.1 and Burst 1.8.18). I’m also using the latest version of Unity LTS 2022.3.55. I can’t upgrade my project to Unity 6 as I’m nearing release and Unity 6 is too big of a change. Breaks too many things in game (I tried already haha).

Is this a bug that only affects things in the editor? Or can it cause problems in a build as well?

It’s a pretty safe bug to ignore. I think it’s caused by unity forgetting to free the last block of their internal queue pool. I don’t think it will cause any issues really. It’s just annoying.
