Found unreferenced, but undisposed Tensor data which might lead to GPU resource leak

[ROBYER1]

Running with Unity 2020.2.3f1 with Barracuda 1.0.4 or 1.3.0 preview in Editor, I get memory leaks and a load of yellow warnings for:

Found unreferenced, but undisposed Tensor data which might lead to GPU resource leak: (GPU:#-169063296 (1, 320, 320, 3) buffer: UnityEngine.ComputeBuffer created at: ) UnityEngine.Debug:LogWarning (object)

and also
''GarbageCollector disposing of ComputeBuffer allocated in D:\UnityProjects\BarracudaUNet2Test\Library\PackageCache\com.unity.barracuda@1.0.4\Barracuda\Runtime\Core\Backends\BarracudaReferenceCompute.cs at line 47. Please use ComputeBuffer.Release() or .Dispose() to manually release the buffer.''

Since this is in the update look, I tried adding m_worker.dispose(); at various points in the update loop and tried it in lateupdate but it didn't help
