I'm noticing a high CPU usages once Substance Launcher indicates I've been logged out.
Normally this is how it will look:

Once I'm logged out of the launcher for whatever reason:

My CPU usage goes up, and even re-logging in wont fix it. I have to close off the application all together.
Additional processes also appear and re-appear after ending at timed intervals.

I'm not 100% sure if it is due to login, or if it is due to the longer the application runs the worse it gets because by the time the CPU usage is that high my login has already dropped.
My CPU is: i7-4790K @ 4.00 GHz
