There is already a topic about the CPU usage, but it’s on Windows (here).
I use the 1.4.15 version, on Ubuntu 18.04 LTS 64 bits.
When I start the application, the CPU starts to warm up, it’s going to more than 100%. Here’is a screenshot :
(I don’t know why I have 2 processus)
Note I don’t open any vault, I am not decrypting or encrypting data : here, I only run the application, and nothing else.
If I close the app, everything returns to normal (the fans of my computer calm down).
I am not sure, but it seems to me I never have this problem with the old versions.
