Continuously leaking 240b textures in ARKit Apps

Hey all,

I’m seeing a stream of 240 B textures leaking into my scene when running an ARKit app. Has anyone else encountered this?





I first thought it was something stupid I might be doing in but looks like it happens in the example scenes that come with UnityARKitPlugin as well. Trying to track down a potential crash and thought this leaky sink might be a good lead.

Any ideas? Is this expected behaviour with a good reason I’m not aware of? Any insight would be greatly appreciated!

[Using Unity 5.6.2p4 with version with version 1.0.9 of UnityARKitPlugin and running on an iPhone 6S Plus with iOS 11.0 (15A372)]

 

Sounds like it's worth to submit a bug-report for it.

 

(Am Gzerg's co-worker) I've found the source:

These Texture2D objects don't need to be created on a per-frame basis. I've changed this class to make the Texture2D.CreateExternalTexture calls only once and profiled the resulting build - now the texture count and memory usage is stable!

Here's a PR with this fix:
