Clipspace Copy + Paste from a "Preview Image" node with multiple images to a "Load Image" node will paste the correct image but *show* the wrong image

[Javalar]

Prerequisites

• I am running the latest version of ComfyUI
• I have searched existing issues to make sure this isn't a duplicate
• I have tested with all custom nodes disabled (see how)

What happened?

After generating multiple images and showing them in a "Preview Image" node (or any similar node), performing in a clipspace copy and paste operation from that node to a "Load Image" node will, most of the time, cause the "Load Image" node to display the wrong image.

The more images are in the "Preview Image" node, the more likely the issue is to occur. At 9 images, it almost always happens.

Note that the "Load Image" node will still use the correct image, it just displays the wrong one.

Switching to a different workflow and coming back fixes the issue (the "Load Image" node now displays the correct image).

This issue is relatively recent, having started a few versions ago. Unfortunately, I couldn't tell you when it started exactly.

Steps to Reproduce

1. Generate multiple images by setting batch_size to a number over 4 in the "Empty Latent Image" node. (9 is a good choice).
2. Select one of the images in the "Preview Image" node.
3. Right click the node and select "Copy (Clipspace)".
4. Right click on the "Load Image" node and select "Paste (Clipspace)".
   The wrong image may be displayed. Try a different one if the issue does not occur.
5. Navigate to a different workflow and then navigate back.
   The correct image is now displayed.

How is this affecting you?

Causes confusion, even the "Load Image" node works as intended otherwise.

Hi @Javalar! I'm Dosu and I’m helping the ComfyUI_frontend team.

This is a known frontend display bug: when you use Clipspace copy-paste from a "Preview Image" node with multiple images to a "Load Image" node, the correct image is used internally, but the node often shows the wrong image. The issue gets worse with more images and is fixed temporarily by switching workflows, which forces a UI refresh. There are no console or terminal errors because the bug is in how the frontend updates widget state and image previews after paste—especially with batch/multi-image nodes. Recent fixes have added bounds checking for Clipspace indices to prevent paste errors and crashes, but the display mismatch can still occur if the widget doesn't re-render from the new data after paste (PR #4849, related issue). The only reliable workaround right now is to switch workflows or manually trigger a UI refresh to correct the display.

To reply, just mention @dosu.
