Lightroom Classic 16.0 – Brief image distortion on first AI Remove selection with GPU enabled

Since updating to Lightroom Classic 16.0, I have noticed a brief ripple-like blur or screen refresh affecting the photograph immediately after releasing the mouse on the first AI Remove selection.

The distortion lasts only a fraction of a second and does not affect Lightroom's interface or panels.

System: Mac Studio M1 Max, 64 GB RAM, Apple Studio Display and LG 4K secondary display.

Steps to reproduce:

1. Open an image in the Develop module.

2. Select the Remove tool.

3. Paint a selection and release the mouse.

4. A brief ripple-like blur occurs across the photograph.

5. Additional selections work normally without the distortion.

6. Leave the Remove tool, return to it, and make another selection. The distortion occurs again on the first selection.

GPU testing:

• Auto: Distortion occurs.

• Custom: Distortion occurs.

• Off: Distortion disappears.

Expected result: The image preview should remain stable when applying the first removal.

Actual result: A brief image distortion occurs when GPU acceleration is enabled.

This behavior did not occur in the previous Lightroom Classic version. The final image appears unaffected.
