I not sure why, buy my graphic card's cooler getting mad, when I'm starting this software. Same I had when tried to generate btc.
What? There's a built-in miner? That would be a first, I think. Way to make "free software"

I doubt it, though, has anyone checked?
That was in v1.4.1.1 because of infinite repainting bug. Now it's fixed by commit
.
There is no neither built-in miner nor any other type of malicious features.
