graphical issues with looking at variables

When I open a variable within matlab to look at it, matrices in particular, if I scroll up or down or left or right, but only with SOME and not others, the screen will get horrible tearing and basically become a mess of blended gibberish. But only within the box where it is displaying the variable, everything else is fine. And when I click away to another tab and then come back to it, it resets itself and looks normal again, until I scroll and it all blends together again.

Does this have something to do with my hardware/OS? I'm currently running Debian.

Which MATLAB version, and which Debian? And which graphics driver are you using?

I see something similar with the installers of old versions of MATLAB when I go to install on OS-X (El Capitan), but that might not have anything to do with what you are observing.

I had to upgrade to Stretch, because the graphical drivers for Jessie weren't working properly for the Skylake processors by Intel. Here's what I was able to find out about my current drivers:

:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 06)
:~$ find /dev -group video
/dev/fb0
/dev/dri/card0
/dev/dri/renderD128
/dev/dri/controlD64
:~$ glxinfo | grep -i vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
  Vendor: Intel Open Source Technology Center (0x8086)
OpenGL vendor string: Intel Open Source Technology Center
:~$

I'm not sure how helpful this information is but I'm not too knowledgeable on this stuff.

Also, I have the most up to date MATLAB version (9.1.0.441655 (R2016b)).

The following workarounds might help resolve the issue:

1. The issue might be due to incompatibility with the graphics library 'libstdc++.so.6' shipped with MATLAB. To workaround this issue, you can rename the library 'libstdc++.so.6' shipped with MATLAB, so that the newer version of the library 'libstdc++.so.6' provided by the operating system is used instead.

Refer the detail steps of the workaround mentioned in the below external bug report: https://www.mathworks.com/support/bugreports/1297894

2.Try upgrading the graphics drivers to the below latest version provided by Intel:
