This demo is a demo written using the new version of blockly, which is basically the same as the demo on the official website.

Hello @tracer1023 it looks like you opened a similar bug previously: #7807 but we had to close it without getting more information.

Unfortunately we are still not able to reproduce this on our touch devices. Can you provide any additional information, such as minimum reproducible example, browser info, etc?

Here is the minimal example code link，develop branch
https://github.com/tracer1023/blocklyDemo.git

You can use webview to open this code on the pad and drag it with one or two fingers in a circular motion, which may occasionally cause finger following problems.

Can you tell us what tablet you are using, and what version of which web browser you are using? Unfortunately we are still not able to reproduce this on our end but we will look into it.

Do you know if this only happens in Blockly v10.3 and above? Or can you try it with an older version of Blockly and let us know if this was a more recent regression? Here's the code demo on version 9.3.1 of Blockly for example, if you could try that and let us know if you have the same behavior, that would be great! A stack trace from that version would also be useful if the problem does occur.

@BeksOmega does the error in the stack trace above look familiar / possible this was introduced by recent dragging changes?

Hi @tracer1023 have you had a chance to look at my last message? Unfortunately without your help I don't think our team will be able to solve this on our own since we can't reproduce it.

Hi @tracer1023 feel free to reopen this issue if you can provide the additional info requested above. Thanks!
