MATLAB R2016b graphics bug (Linux)

Hey everyone,

I'm facing some weird graphics behaviour when I try to display variables or output variables to the command window. The GUI gets completely messed up, see the screenshot.

I'm using R2016b on Ubuntu 16.04. Opengl seems to work:

                          Version: '3.0 Mesa 12.0.6'
                           Vendor: 'Intel Open Source Technology Center'
                         Renderer: 'Mesa DRI Intel(R) Kabylake GT2 '
                   MaxTextureSize: 8192
                           Visual: 'Visual 0xe7, (RGBA 32 bits (8 8 8 8), Z depth 16 bits, Hardware acceleration, Doubl…'
                         Software: 'false'
             HardwareSupportLevel: 'full'
        SupportsGraphicsSmoothing: 1
    SupportsDepthPeelTransparency: 1
       SupportsAlignVertexCenters: 1
                       Extensions: {231×1 cell}
               MaxFrameBufferSize: 8192

Does anyone have clue what the problem could be?

Thanks!

Use Software OpenGL Instead

You can work around many graphics issues by using the software version of OpenGL® built-into MATLAB instead of using your graphics hardware. In some cases, MATLAB automatically switches to software OpenGL, for example, if it detects known issues such as outdated drivers or graphics virtualization. Software OpenGL does not support some graphics features, such as graphics smoothing.

To switch from hardware to software OpenGL, start MATLAB from the command prompt on your system using this command:

matlab -softwareopengl

To set your preferences so that MATLAB always starts with software OpenGL on this computer, execute this command at the MATLAB command line:

opengl('save','software')

Use OpenGL Compliant Graphics Hardware

For the best results with graphics, use graphics hardware that is compliant with OpenGL 2.1 or later. For more information about the graphics features that different versions of OpenGL support, see System Requirements for Graphics. Upgrade Your Graphics Hardware Drivers

Graphics hardware vendors frequently provide updated graphics drivers that improve hardware performance. To help ensure that your graphics hardware works with MATLAB, upgrade your graphics drivers to the latest versions available.

Check your computer manufacturer website for driver updates, for example, Dell® or HP®. If no updates are provided, then check your graphics hardware vendor website.

If you saved a setting to always start MATLAB with software OpenGL, then after updating your drivers, you can revert that setting by executing:

opengl('save','hardware')

Then, restart MATLAB.

I have the same issue and I already use software opengl version, it doesn't fix

[Ulrich]

I run a Fedora system, and have the same issue. I can confirm that the software opengl version DOES NOT fix this issue!

I am also trying to use Matlab 2017a with Ubuntu 18.04 and the opengl version does not fix this.

[rick_deckard]

I have the same issue, and terminal already reads "MATLAB is selecting SOFTWARE OPENGL rendering."

Matlab 2017a, debian stretch.

[maxime ferez]

hello everyone, I'm working on ubuntu 18.04.3 LTS and matlab R2017a. I have the same problem. Did someone find the solution to resolve this problem? Because I tried the different answers and it doesn't work

Thanks

This issue was discussed in another post. I had the issue, but was able to solve it. Set the following environment variables (change the XXX to the correct version installed). If it works, add these lines to your .bashrc script.

export J2D_D3D=false export MATLAB_JAVA=/usr/lib/jvm/java-XXX-openjdk/jre

[Ulrich]

Quick test shows that this does not fix the issue on my fedora machine

[Shannon]

That solution did not solve the issue with ubuntu 18.04.

[rick_deckard]

Michael, can you post a link to the previous discussion that you mention about? And also where did you learn about your fix method of adding that line to .bashrc script?

[Michael Corbett]

Here is the link .

In the fix, the "export" command is used, which I knew to be a command used in the .bashrc.
