Hi there, Sorry to learn about this. Would you mind sharing a screenshot of how it looks at your end? Does it happen with a specific pattern? Could you share some workflow steps, so that we ay try to replicate the problem at our end? You may try resetting the preferences of Photooshop and see if it helps:

Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. https://helpx.adobe.com/photoshop/using/preset-migration.html
