I've found a way to bypass this annoying bug, thanks to the documentation
available at https://wiki.archlinux.org/index.php/Intel_graphics

More than a week has passed without suffering the failure, since I implemented
the change suggested there :)

In summary, I created the file /etc/X11/xorg.conf.d/20-intel.conf with this
content (I left some commented lines as a reference to other possible
workarounds that I didn't test):

# content of file begins here                                                   
Section "Device"                                                                
  Identifier  "Intel Graphics"                                                  
  Driver      "intel"                                                           
  Option      "AccelMethod"  "uxa"                                              
  #disabling the GPU usage with the NoAccel option                              
  #Option "NoAccel" "True"                                                      
  #Alternatively, try to disable the 3D acceleration only with the DRI option
  #Option "DRI" "False"
EndSection
# content of file ends here                                                     

If you know about another solution or alternate configuration, I would like to
know the details.

Thanks!
