AMD GPU Material in "material preview mode" and "rendered mode", is entirely gray as background. Only outline is displayed I don't know why but now, when i go in material preview or rendered (in solid mode it works fine), my object is entirely gray, or invisible idk, because it has the same color of the background.
I've been working for days on this project without having this issue, it suddenly showed up.
I tried opening other old projects and suddenly they all do the same so i guess it is some blender program setting that applies for all the projects, but idk how it happened cuz i didn't change anything :/, anyone got any tips?
Update: Blender 2.92.0, 2.91.1 and 2.83.11 will contain workarounds for the missing / incorrectly rendered surfaces of mesh, curves and metaballs as well as the incorrectly rendered wireframes caused by bugs in the graphics driver.

The graphics driver version Adrenalin 2020 Edition 20.11.2 and later appear to cause issues for several users, as reported in T82856 and related tickets. Installing a previous driver version should solve these problems until the bug in the driver is fixed or Blender provides a workaround for the problem.
