Short description of error
The Material Preview doesn't show on Propierties Editor > Material Properties > Preview Panel.

Exact steps for others to reproduce the error

Open the default startup file.
Immediately go to Properties Editor > Material Properties > Preview Panel and open it (don't move the view in the viewport).
The window of the material preview shows blank, I wait a long time (more than 2 minutes) but nothing happens.
This happens with Eevee and Cycles.

NOTE 1: If you scroll down the panel to hide the material preview window and then scroll up to show the material preview window, the preview of the material appears. This happens with both, Cycles and Eevee.

NOTE 2: With Cycles selected like render engine and the Preview Panel open, if you move the view in the viewport the material preview appears.

NOTE 3: Recently I changed the original graphics card (Radeon HD 6970M 2 GB GDDR5) of my iMac 27" i7 mid 2011 for a NVIDIA Quadro K3000M, I don't know if this can influence but with Blender 3.0.0 all work fine.

Based on the default startup file.

Hi, thanks for the report. Can confirm here on Windows.
I will check.
Broken between 713d59bcafb1- e6ca0b33e9
Edit: I'm getting an error while bisecting (need to fix, will raise the priority for now)
