Blender Version: 2.91 (also 2.83)
GPU: Radeon RX 590 (with and without updated drivers)
I stumbled upon the problem in another context which lead me to a way to recreate the glitch in a clean file:
- Open Default File (named General)
- Go to the material of the default cube (in Solid Mode)
- Under Viewport Display go to Color and set the Alpha to anything else than 1
- Add a new material
This creates the glitchy mesh seen in the image below.
My viewport shows weird noise when I toggle x-ray mode only in solid view.
I had In Front (under Object Properties>Viewport Display) enabled for my mesh and after a lot of searching I found out that I can toggle the glitch by disabling that.
I cannot seem to recreate the glitch in a clean file though and I'm a bit afraid that something is broken in my file.
Things I tried before the "In Front" toggling:
- deleting all vertex groups, materials, modifiers and all other objects in the file
- switched from smooth to flat shading
- cleared all marked edges
- disabled auto-smooth
- disabled all addons (and later used a clean install)
Changing the workspace resets the view but the glitch returns on toggling x-ray view.
At least when I export the mesh as an FBX file that seems to be glitch-free. Though that way I lose all my vertex groups.
Any ideas what is happening here?
