PC: Ubuntu Latitude E6420 Core i7 2.8GHz 8GB ram

Ubuntu 16.10

After I close my laptop or manually suspend session, when wakeup it becomes terribly slow. Reboot solves it, but becomes unpractical. Anyone knows any fix for this? Not sure what it is causing this bug.

EDIT: I upgraded to 17.04. Before upgrading, I noticed that when after wake I get some glitches bellow opened windows and bars. After upgrade, all is the same.

after waking up - glitches bellow opened windows

desktop look after minimize all opened windows
