Sounds a whole lot like #77944 (Material Preview (and final render in EEVEE) purple)

@fclem: I cannot reproduce, but does this ring a bell somehow?

What is the output if you launch blender using the debug and debug_gpu batch files?

As described in #77944 (Material Preview (and final render in EEVEE) purple) I get pink/purple color several times too: Resizing the preview panel size is not the only way to produce purple color. I can confirm these effects:

#77944 (Material Preview (and final render in EEVEE) purple):

pening a preview (in my case the material icon becames purple here, but the preview itself often can be normal yet in 2.83)

changing a Preview Render Type (it "paints" the object and the plane unpredictably, but most times it's purple every time when switching, as in screenshots in the description. For example, every part of a Shader Ball can be either grey or purple color)

changing something in material shader (for example, a Base Color)

using Material Preview viewport shading

Render itself

On rare conditions preview rendering (and eevee rendering) works fine. Unfortunately, I cannot make out specific conditions to get purple or correct preview colors. Changing the preview size leads to purple colors every time!

In my opinion this ticket can be marked as duplicate of #77944 (Material Preview (and final render in EEVEE) purple).
