BUG: CPU High after Curve Use

[SebNik1]

• Describe the bug: As soon as I use any of the curves (the tools below the line tools) my projects will start to consume high cpu rate and my macbook fans run full power
• How To Reproduce the bug: Construct anything with a curve in it
• What should have happened: No unusual high CPU usage or fan running
• Screenshots
• What's your Desktop OS? MacOS 11.7.4
• What's your Seamly version from Help/About? _Seamly 2023.2.13.238

First of all thank you very much for seamly2d, I very happly use it for over two years now. I have experienced the same problem with the curves before but as it persists I would like to kindly bring it to your attention. As soon as I use any of the curve tools Seamly2D starts using very high cpu usage. This persists even after deleting the curves again with no curves remaining in the construction. My Macbook Pro is a late 2013 with i7 2.3Ghz and 16GB of RAM. In regular cases seamly2d doesnt use more than 5% CPU at the max.

Maybe you can try reproducing this. I'd be very happy to hear from you.

P.S. in Addition I got trouble with the color scheme, if this is a user setting I'm sorry to trouble you:
