Hello Makitso, *,
I cannot confirm it with

OS: Debian Testing AMD64
LO: Version: 5.1.4.2
Build-ID: 1:5.1.4~rc2-2
CPU Threads: 4;OS Version: Linux 4.5; UI Render: default; 
Locale: de-DE (de_DE.UTF-8)
(Debian's own version)

nor with

LO: Version: 5.2.0.1
Build ID: fcbcb4963bda8633ba72bd2108ca1e802aad557d
CPU Threads: 4; OS Version: Linux 4.5; UI Render: default; 
Locale: de-DE (de_DE.UTF-8)
(parallel installed, following the instructions from https://wiki.documentfoundation.org/Installing_in_parallel/Linux)

and

# hwinfo |grep Graphics
     str1: "Video Graphics Controller"
E: ID_MODEL_FROM_DATABASE=Haswell-ULT Integrated Graphics Controller
   Video: "Video Graphics Controller"
   Model: "Intel Haswell-ULT Integrated Graphics Controller"
   Device: pci 0x0a16 "Haswell-ULT Integrated Graphics Controller"

using xserver-xorg-video-intel 2:2.99.917+git20160522-1.

Just out of interest: is "Use OpenGL on all Rendering" or "Force OpenGL even if blacklisted" in "Tools - Options - LibreOffice - View" enabled on your system? If so: have you installed any glx, opengl, mesa, etc. packages? Do they work with other applications? What happens, if you disable them?
HTH
Thomas.

Thanks Thomas.  Yes, I have glx, opengl, mesa packages installed, not sure why.  
Checking and unchecking the use OpenGL options does not help.  I will try with a clean system.

OK, I have found a solution but really by accident. 

Tried a stock 16.04 xubuntu system and no sign of the problem.  Then install all the applications on the stock system and still no problem.  

Then back on my base system I noted that with the Intel Corporation Broadwell-U Integrated Graphics card I run the resolution at 1600x900 as opposed to the standard 1920x1080 resolution.  So, I change the resolution to 1920 and the problem went away!!  Then changed the desktop resolution back to the 1600x900 and the problem no longer exists!
Comment 6 makitso 2016-09-15 18:50:53 UTC 
Well, the problem is back and the workaround I mentioned before is no longer any help.  Version is 5.2.1.2.
Comment 7 makitso 2016-10-21 19:02:00 UTC 
I understand that this is a video driver problem.  I tried a newer kernal and no change.  But i tried xubuntu 16.10 and that fixed the problem. For some reason the video driver (lspci) is different than 16.10, so i upgraded.

However, i never found any other application that failed except Calc.
