System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon RX 560 Series ATI Technologies Inc. 4.5.13596 Core Profile Context 20.10.35.02 27.20.1034.6
Driver version: 27.20.1034.6

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-07-01 12:26, hash: a112adf16a (Also present in 2.93)
Worked: Unkown

Short description of error

When resetting the Viewport display color of an object, the screen glitches out and starts showing artifacts.

Original:

After Glitching:

Exact steps for others to reproduce the error

Open the attached blend file
Select the "buildings" object
Open the Material Properties Tab
In the Viewport Display separator hover over the color picker and press the backspace key

glitch.blend

Additional Notes

For this to work the "domain" object must be present, otherwise the functionality works as expected.

Both objects were imported from a STL file.

I tried to update the graphics card drivers to the latest version, but with the latest version of the AMD drivers the system became so unstable that the driver crashed a few minutes after booting. So this report does not use the latest AMD driver.

The driver version I'm using was auto installed by windows, and I can't find the version I was previously using (which also showed the crash), but it was more recent than this one.

I can reproduce this on 3.0.0 (4ba06ad0a8)
I think the issue is specific to AMD gpu.

This looks like #83022 (Transparency in Solid View Causes Glitch Artifacts).

Resetting to default value will give an alpha of 0.8 (which is not ideal, but this is a different story).
Since #83039 (Workbench: display corrupted in 2.91 with file from 2.90) was also merged into #83022, I think this should be done here too, so will merge these reports.
