in 2.90win10. at start screen assign a quick effect liquid domain to block. both change to wireframe. hit play and animation shows properly in 3d view. delete liqid domain. block still shows as wireframe. select solid shader for 3d view and block still shows as wireframe. cannot get block to show as anything else but wireframe in any editor.
same problem is not apparent in 2.79b which i am running on my minimac.
