I am using Proton Mail Desktop application on a Windows 11 ARM (Snapdragon 12-X core) and I find it painfully slow.
Navigating through emails takes forever. I am forced to open the web most of the time when I do things quick. I can see it is still running x64 cause there is not distribution for ARM64.
On top of that it is using a crazy amount of resources:

I was wondering if there is a way to build the app myself and eventually tweak it to optimize it a little bit.
