Terminal is freeazing after screen saver

[5k18a]

I noticed that in new version of Aster, terminal which is getting back from screen saver mode is freezing. The same thing is happening in Steam application when full screen video is playing (from product page). When I'm trying to come back from full screen mode terminal always freeze. Mouse is not responding but sound is working. Combination of ALT+F4 probably is working because I can get "bell sound",CTRL+ALT + DEL don't work and the screen is black. At that time other terminal worked well. To restore terminal I can only reboot computer from second terminal.
