Editor is lagging when modifying material properties

Graphics - General


How to reproduce:
1. Open attached "ForgottenPlayhouse" project
2. Select "cardboardwall1" material under Assets/Materials/Cardboard/CardboardWall1
3. In Inspector change color of the material

Expected result: Color(or any other property) is changed instantly and Editor does not lag
Actual result: Editor is lagging after every property change

Reproduced with: 2018.3.0b7, 2019.1.0a10
Does not reproduce with: 2018.3.0b6 (performance is only barely slower), 2018.2.17f1 and lower (performance is as expected)

Notes: Changing the Shader from HDRP to any other still reproduces the issue.

    Or just cache it. I hacked around this by skipping CreateCustomShaderEditor and replacing it with a cached one.

    The cause of this bug is that the ShaderGUIUtility.ExtractCustomEditorType() function is looping through all types in the loaded assemblies, even though it's only looking for a specific type name.

    Fix: Swap this loop with Assembly.GetType() which is O(1) for a given type name.
