Please give a brief summary of your issue:
We integrated your pixel by pixel comparison feature using the related documentation, and we face a performance issue related to the accuracy in the middle generated instance once we zoom a lot, in comparison to what you propose in your demo:
It seems that our generated middle instance comparison loads, but at some point it has zoom rerender capacity limits (like blurred) and it doesn’t load more anymore, while for your demo it is more powerful.
If it may help, we have multiple errors in the Console:
It seems you also have the “Cannot cancel callback undefined” in your demo, but in addition, on our side, we have the “functions-to-override.js:1005 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘polygon’)”.
And this occures multiple times each time we zoom.
Could you please explain us why do we have such a limitation, and if some specific code could tackle that, please?
Thanks in advance for your time.
