Assertion failed error with HDRP

Hello !
I have a problem on my project in which we use HDRP.
When navigating in our scene, we have the following error :

Assertion failed on expression: 'reinterpret_cast<size_t>(dstPtr) >= m_BufferSize'

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

The error occurs in HDRenderPipeline.cs, line 1767 :

renderContext.Submit();

Every camera movement (in editor mode) is producing hundreads of errors.
Do someone have any idea why this is occuring ?

Thank you

 

Hi, I am using Unity 2019.3.2f1 with HDRP 7.1.8.

It happens all the time in a specific heavy scene.

I filled a bug report in which I attached the scene

EDIT : The error happens everytime something in the scene is edited, not only when camera is moving. When I select a gameobject in the Hierarchy, when I rename an object, etc.

 

I have the same error on a scene that contains very large amount of planes that act as grass on the Unity Terrain. I am also using Terrain Tools.
Unity 2019.4.14f1, HDRP 7.5.2, Terrain Tools 3.0.2-preview.3

Full Error:
"Assertion failed on expression: 'reinterpret_cast<size_t>(dstPtr) >= m_BufferSize'
UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)"

How to re-create:
Paint large amounts of trees(Each has 4 planes, an albedo texture and a normal texture applied) on a terrain.

 

I see the same error on scene that loads 5000 instances of plants. The error stops after a couple of thousand errors and then reports no more errors. Unity 2021.2.11.f1 with the latest HDRP.

In the game build there is no errors. Must be an editor thing.
