# SUMMARY
I encountered a program crash after overwriting gradient resources.

I have a suspicion that the previous fix didn't actually resolve the root cause but only masked it. The issue re-emerged when I was working on multiple files at the same time.

After several attempts, I have found a consistent way to reproduce the issue:
1. Open Krita and create a new document.
2. Draw a stroke on the layer, then open the "Layer Styles" dialog.
3. Enable "Gradient Overlay", set the "Blending Mode" to "Normal" and "Opacity" to "100%". Create a new gradient preset, keep the default name (do not rename it), and click OK.
4. Re-enter the "Layer Styles" dialog and change the "Angle" of the Gradient Overlay to a random value.
5. Close the document without saving, then create another new document.
6. Open "Layer Styles" in the new document, create a different gradient effect but keep the same default name as before, then click OK.
7. The application crashes immediately.

I cannot reproduce the crash/assert here. But if I create two layers with different gradients names "unnamed", then after reloading both layers will have the same gradient, even though both are loaded.

I tried again, but the issue persists. I might have missed a step in my description, so could you please check the video? My apologies for forgetting to set the permissions to public earlier: https://drive.google.com/file/d/1mZhAHcYj3OC0Xzowc9vEbBohLRWhfTBQ

Hi, SharpIce!

Could you please also retest with the official AppImage?

I've tested this on both AppImage and Windows 11, and the issue persists. After checking with a few friends, it seems to work fine on X11.

Below is the terminal log generated while running the AppImage:
