I import a WMF vector graphic than divide a plot in single points; it keeps working for more than 15 minutes and had to kill the program.
Steps to Reproduce:
1. Open WMF graphic
2. select the graphic and perform "divide" command until reaching a plot
3. dividing the plot in sigle dots takes a huge amount of time and require killing the program
Very slow process
The process should take a few seconds

I selected the topmost plot and right-click - Break. I took maybe under 1 minute. This is on a 2012 laptop.
Lucio: how performant is your computer?

I first tried on a Core 2 duo, now just tried again on an Intel Core i3 always under Ubuntu Mate 64bit. Breaking the first plot took 6 minutes (100% workload for 1 out of 4 CPUs), then I tried to move the plot and it started again 100% CPU and causing the mouse to stop working until I had to kill the process.
Buovjaga, I see you're using Windows; maybe this is a Linux-only issue...

I don't know, those CPUs sound slower than my 2012 laptop, which has i7 of its generation.
I do confirm in

Each line has about 20000 points. The handling of so many points is not a matter of the speed of the processor but of the size of the memory. If the memory is 4 GB or less, it sometimes helps to close all other applications, especially browsers. I've got 16GB RAM and breaking all graphic is done in 16 seconds. There have been some improvements in handling huge amount points in charts, but I do not find the issue, might have been in earlier AOO.
It does hammer the CPU on Linux (breaking the topmost plot). I have 32GB of memory. I killed it after 2 minutes.
Please everyone test on Linux.

I confirm the problem is still present in Libreoffice Draw 184.108.40.206 running in Ubuntu Mate 18.04.1 on a Dell XPS 13 with 7.5Gb of RAM and a Intel Core I7-8550U CPU (1.8GHzx8): one of the 8 cores keeps working for more than 2 minutes, than I killed the process.
