Hi @david,
Thanks for the recommendation. Since then I had adopted “lighter” tabs and had adopted a 1-year trailing view. That fixed the memory crash on laptop.
I had completely forgotten about this bug report post until I saw this one (Intervals.icu library update complete!). I went back to my previous view (with tons of charts and 4 years of data) and I can confirm it does not crash anymore. The faster (almost instantaneous) rendering is the cherry on top! Great job.
Thank you for the hard work,
Laurent
