small local changes in node position have unexpected global effects

[chrisesposito4]

Hi,
I'm seeing a problem in network redraws that I can reproduce. I have a reasonably sized network, maybe 50 nodes and 100+ edges. If I have a task node that has 1 input and 1 output (so not directly connected to the rest of the network) and I move it by a very small amount (a few pixels in any direction) then the edges in distant parts of the network are rerouted in a way that makes the network layout vastly more cluttered - edges get longer, less direct than they were, and with more bends. The node stay where they are. Is there a setting I can turn off for this? It seems to me that moving a single node ought to only affect the edges it is connected to.

Hi,
I guess you are working in a diagram without pools? I observed this behavior also but was not able to reproduce it directly.
I think this is a regression in our new 'optimized' routing algorithm.
Can you try the last release 1.1.24 - you can install this extension as a vsix file

https://github.com/imixs/open-bpmn-vscode-integration/releases/tag/open-bpmn-vscode-integration-1.1.24

Please let me know if this helps.

Sure - I’ll give it a try tonight Sent from my iPhone On Jan 12, 2026, at 1:18 AM, Ralph Soika ***@***.***> wrote:  Hi, I guess you are working in a diagram without pools?

I was able to isolate the bug with a simplified model file. So now we can better analyze what is going wrong here....
