Since upgrading to 2019.2 alpha, I have had some errors occurring and a bunch of garbage collection warnings repeatedly.
Errors:
Recursive rendering is not supported in SRP (are you calling Camera.Render from within a render pipeline?).
Assertion failed on expression: '!GetPersistentManager().IsStreamLoaded(metaDataPath)'
Asset import did not unload metadata path. This will leak memory. File a bug with repro steps please. (Assets/Prefabs/Parts/Hands/Cannons/Gauss Cannon.prefab)
GUI Window tried to begin rendering while something else had not finished rendering! Either you have a recursive OnGUI rendering, or the previous OnGUI did not clean up properly.
Assertion failed on expression: 'device.IsInsideFrame()'
Warnings (many, repeatedly, even with nothing in scene):

I don’t know if the erroneous metadatapath prefabs (often containing new VFX effects) are connected to the hdrp garbage collector issues.
I’m sure I have missed out something useful for helping to get to the bottom of this so please suggest anything I can do to help debug this!
My project is becoming unworkable at the moment, the play/stop functions take 10x longer than usual, and this gets progressively worse over each session.
Thanks in advance!
