I'm using a Linux guest (Ubuntu) on a Windows 8.1 host as my main workstation.
(I also have other VMs as test machines).
The extension pack is installed and up-to-date.
I have a dual monitor setup, with the guest's virtual screen using host's screen n°2, in full screen (auto size)
It's been working just fine until this morning : the Unity desktop (Ubuntu) is just desperately slow ; menus and windows fading, switching desktops, etc. are very slow.
Minimum info :
VirtualBox 5.0.14r105127
Extension Pack Version: 5.0.14 r105127
Host : Windows 8.1 (Intel core i5 ; RAM 16 GB)
Guest : Ubuntu 12.04 (2 CPUs ; RAM 8 GB)
I'm not sure if this is related, but I installed (dot)NET framework 4.5 this morning, while the guest was running.
I had just started the guest and had not yet been working on it, so I can't tell if it was already slow or not, though I thought the startup took longer than usual.
I updated the nvidia video driver on the host, just in case.
I also updated Avast on the host, and excluded the folder where the VMs are stored.
I also noticed warnings and errors in /var/log/Xorg.0.log (on the guest) :

Thanks in advance
