@maocatooo 感谢提问题，可以提供复现路径或者环境吗，这个可能是特定环境或者特定操作产生的 bug.

抱歉这么晚才看到回复

在https://drawnix.com/ 上传图片进行拖动时出现的问题

具体操作流程 上传图片后，按住ctrl键+鼠标滚轮放大缩小，然后拖动图片，出现残影

我还发现出现残影后，再次进行放大缩写后，残影消失

@NaoCoding 你那边帮忙尝试下，看看能否稳定复现吗，我这是 mac 触摸板，没有鼠标？

[NaoCoding]

hi @pubuzhixing8 我可以嘗試看看
但這個 issue 先維持開著可能比較能夠追蹤？

[NaoCoding]

@pubuzhixing8 的確現在有這個問題。
但是我還不太確定確切的原因

等你有时间可以协助排查下，我这不是很容易复现。

hi @pubuzhixing8 , 我嘗試去復現並去解決問題，但是我目前只確定現在的版本還是存在這個問題，不知道產生問題的原因

I retested this against develop at b138ff8 (Plait 0.94.0), but have not obtained a stable reproduction of the reported image trails.

The checks followed the reported sequence: add an image, zoom with Ctrl + mouse wheel, then drag it. They covered normal and high zoom (including 400%), slow and fast movement, and inspection both during dragging and after release. Automated checks used Chromium 147, Firefox 148, and WebKit 26.4 on Windows; a local canvas was also checked manually. No matching trails were observed in these runs.

A separate check using Chromium 141 and Plait 0.92.1 also did not reproduce the trails. That check retained current Drawnix source and the other current dependencies, so it was not a complete historical build.

This is an investigation result, not a confirmed fix. No production code was changed, and these results alone do not justify closing the issue.

If this still occurs, could you share a small example image or .drawnix file, the browser/OS versions, browser page zoom and system display scaling, and the canvas zoom when it happens? A recording of the exact steps on the current version would help distinguish the missing trigger from an environment-specific rendering problem.

AI assistance: Codex/GPT-6 Astra assisted with the investigation, automated checks, and drafting this comment.

I just re-test this issue and I think the issue still occur.

I use a random image and I have saved the drawnix file(but it seems that I cannot upload it on the github issue comment, maybe I need to paste in via discord?)? the OS is windows 10, with browser Brave.
