Try this solution proposed by dromnia86 on
https://www.reddit.com/r/elementaryos/comments/34dm4t/fixrestart_corrupted_mouse_after_dragging/
It worked nicely for my machine.
# Create the file 20-intel.conf in /usr/share/X11/xorg.conf.d/
sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf
# Paste the following into the file and save it:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
# Restart the machine
# If this plays havok with your brightness on your display, reopen the file and
change it to:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
His post also talks about a potential solution for screen blanking after
waking from suspend, so check it out if that affects you too.
I hope this helps.
