Short description of error
Creepy broken pixels over the 3dviewport, just in the background itself, is not affecting how the mesh looks/draws or the UI elements (and gizmos)
Also is very related to the 'in front' option in viewport display but is not about the other known issue about 'in front' option that makes weird effects in the faces of the model.
This weird effects every time has triggered (randomly) to me while modeling (edit mode) and is transfered to other modes and to other workspaces as well (but not all of them).
I found that If the the effect is triggered when turning on in front option or tweaking the viewport display options (Display as... ) while in front is active, it will stay there even when turning off in front option later
My graphics card is new and drivers are updated so if it's about a graphic card issue maybe is about a compatibility issue with amd(?
When Changing modes and workspaces
