Why does the countertop flicker with shadows

When there is flickering on the kitchen countertop, there are two possible reasons:

First reason: The countertop installation is overlapping. Creating the countertop twice will cause it to turn black. Right-click on the countertop and select Delete;

Second reason: Overlapping cabinets are causing the issue. You can resolve this by following these steps:

• Step 1: Right-click on the countertop and select Delete;
  
• Step 2: Delete the overlapping cabinets and reposition them;
  
• Step 3: Right-click on the wall, select Countertop – Install countertop;
  
• Step 4: Choose the material and click OK.
