Performance issue when dividing a task

[Strubbl]

When i want to change the polygon size in the divide tab, i want to enter a value into the field, e.g. instead of 1000m² i want only 640. I start typing 6 and then my browser freezes. It says result with 4900 tasks is too big, only 1000 allowed. The browser is stuck then. Is it generating the preview? I cannot do anything with the tab anymore and Firefox proposes to stop the scripts on that size.

It would be nice if i can manually enter the polygon size value without my browser freezing.

step to reproduce:

1. create a project
2. enter name for the project
3. use pencil tool to draw a polygon approx. the size of Hamburg
4. go to tasks tab
5. click on that task
6. in subdivide click preview
7. change the 1000 to e.g. 640

Hi, thanks for this problem/bug report.

To your question: Kind of. The drawn polygon is internally divided to calculate the expected number of sub-polygons. A better solution would probably be to either make this smarter/faster (if the framework allows that), to stop dividing, when the threshold of sub-polygons is reached or to move the calculation to the server (which might calculate the sub-polygons faster than the frontend).

I added this issue to the 1.4.3 project and hopefully find a solution soon.
