Artifacts with OpenCL on.

[RichardMH]

NVIDIA GeForce GTX 1650 SUPER. OpenCL acceleration on. Windows 11. Studio driver 472.39. Artifact only on top layer when I Merge Visible. Done a few edits with OpenCl acceleration on and it hasn't crashed yet. Thought  I was home free. In LAB colour space. 1.10.4.1198.

Hi @RichardMH,

If you disable openCL are the artifacts still present?

Haven't had any problems with OpenCL off. Just reloaded the affinity file with OpenCL off, turned the layer with the artifacts off and reran Merge Visible and its fine. With OpenCL on I get artifacts every few tries when I do this. Also with OpenCL on if I copy flattened (with the problem layer off) and use New from clipboard I get artifacts.

You might want to try a clean install of your graphics card drivers, making sure to install the latest ones and then try enabling OpenCL again in Affinity.  Performing a clean install of the drivers has been known to resolve issues with openCL.
