Hi Imran,
āSorry for the late reply due to the holidays!
Is the situation any better at the moment?
Iām really sorry this is happening. This is a bigger thread that complains about a similar issue: Dynalist using a ridiculous amount of RAM (Windows Desktop App)
We have plans to update Electron and see if that can fix it.
I wonder why itās happening in Safari though, that makes it seem like itās a somewhat different issue.
