no clone stamp preview in mask

Hi ​@michaljanata, Thanks for reaching out to the Photoshop Community Forum! Let's try a few things and see if we can fix the clone stamp.

1. Check Layer Mask Visibility: Ensure that the layer mask you are working on is selected and active. Sometimes, the visibility of the Clone Stamp source preview can be affected if the layer or mask is not properly selected.

2. Adjust Clone Source Settings:

   • Go to the Clone Source panel by navigating to Window > Clone Source.

   • Check if the overlay option is enabled. If not, enable Show Overlay to see the source preview.

3. Verify Tool Settings:

   • Select the Clone Stamp tool (S) from the toolbar.

   • In the Options bar, make sure the settings such as Size, Hardness, and Blending mode are set appropriately for your cloning task.

4. Reset Preferences: If the issue persists, consider resetting Photoshop preferences - https://adobe.ly/3W7zc6U

   • Remember to back up your settings before doing the preference reset: https://adobe.ly/4e0UkBL

If none of these steps work for you, please let us know, and we can continue troubleshooting. I hope this helps! ^CH
