System Information
Operating system: Darwin-18.6.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon RX 580 OpenGL Engine ATI Technologies Inc. 4.1 ATI-2.9.26

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-04 22:24, hash: fdcfc263e9
Worked: (optional)

Short description of error
Adding a material in look dev mode sometimes makes interface very slow

Exact steps for others to reproduce the error
I have a scene with multiple materials. Sometimes when I add a material on an object, the interface becomes very slow. If I swap this material with another, the interface is responsive again. Can't figure why. It seems to be Mojave problem only I think (No problem on High Sierra with an old GTX780)

Open the blend file I uploaded. Select the object "Wheel". Add a new material = Slow performance.
Put the material named "Carrosseie" for example on it and there is no performance issue.

I can't reproduce this on linux, so I'm guessing this is a mac issue.

@WilliamReynish can you reproduce this?

With the scene "CarGPSimpleBug2"
When I use the "Pneu" material or "Material.004" on Plane.014 viewport becomes laggy every time.

CarGPSimpleBug3.blend :
Unhide object wheel.001 = performance issue

Tested with RC1 and this the same problem. Is my config not capable of handling such a little scene in 2.8 ?
2 x 2,8 GHz 6-Core Intel Xeon
24 Go 1333 MHz DDR3
Radeon RX 580 8 Go

If I remove material.004 and material "pneu", the performance is ok. The massive slow down comes back as soon as I add a new material.
Have I no other choice but to stay with 2.79 ??

SimpleBoolersBotBUG.blend

Tested with another scene "SimpleBoolersBot" which is extremely laggy too:
2 possibilities to recover from the extremely slow performance

1 - In the scene collection MASTER/Objects: hide Cube.011 and Sphere.001 = good performance.

OR (reopen the file if needed)
2 - From the Outliner / Blender file: delete Material.001 = good performance.

It seems like a bug for me or an incompatibility with my OS/hardware... As a long time user of blender, i have never encountered such slow downs that I couldn't figure why (sorry for my english)

Found a workaround !!!!
Replace Principled BSDF with a glossy or diffuse shader for the materials that have an impact on the performance. Everything runs smoothly.
I will continue to look for the parameter in the principled BSDF that makes the interface slow. Perhaps I will find something.

I can also reproduce these same kinds of issues, where performance counter-intuitively fluctuates wildly based on seemingly unrelated and arbitrary adding or removing objects.

@WilliamReynish so you can reproduce this? Perhaps we could mark this as confirmed then?

@WilliamReynish : Can you reproduce the performance issue with the files I uploaded ? Have you a file I can test ? I am here if you need.
Having to replace the BSDF shader with standard shaders or having to delete objects to recover from performance issues is a pain (even if I can live with it...) This a lot of trials and errors.
I hope somebody will confirm someday and that a fix will be found...

Eevee has serious problems on macos. Simply adding a few materials can reduce the number of frames when the viewport plays the animation. Simply dragging the viewport is also severely stuck, but this should not be a performance issue. , Because in the viewport, hold down the middle mouse button for five seconds, you will find it becomes very normal, but only hold down the middle button, once you release the middle button, or ordinary moving perspective, the kind of stutter is intolerable of,.
