Shutter locks up the whole system for a few seconds after every capture
Possibly changing my settings - e.g. disabling automatic copying of screenshot to clipboard - would help; I will try to test. I did not have this problem until recently. (Perhaps the upgrade from Miny 18 to Mint 18.1 has something to do with it?)
Linux Mint 18.1 x64. 8GB RAM. SSD. Intel Core2Duo processor. Intel graphics.
Shutter 0.93.1 rev. 1278
EDIT: I think it *is* the copy-to-clipboard setting. Or at least enabling that settings takes a barely noticeable delay (caused by my having the sale-to-file setting enabled?) and makes it into a more noticeable one.
