In Ubuntu 16 I was able to press Shift PrintScreen and select area on the screen to screenshot it. In Ubuntu 18 when I press Shift PrintScreen the similar mouse icon appears and I also can select an area. But on finish nothing happens, no application appears to have my screenshot inside.
How to restore old functionality?
Note, that I don't want to manually start
screenshot application beforehead and press GUI buttons inside it, I want to have work done on Shift PrintScreen.
