16518,5.1.14 verry slow on 4770k (5.1.12 and older are faster),LMS23,,"Since the update to 5.1.14, my virtual machines are slower than before.

It affects both Windows (Win7 and Win10) and Linux (Ubuntu/Lubuntu 16.10) guests. 

It is mainly about the user interface, this is noticeably slower. I tried it with and without 3D acceleration.

After a downgrade of the VirtualBox (5.1.12 or older) the systems are faster again.

My Setup:

- Intel i7 4770k @ 4 Ghz
- 32 GB RAM (4x8)
- GA-Z87X-OC
- All VM Disks on SSD
- Windows 10 PRO 1607
