Graphics glitch Ubuntu 17.04

When viewing a large vector/variable in the workspace the output looks like this. This problem have been consistent on multiple machines running both Ubuntu 16.04 and 17.04, with matlab R2016A, B and 2017A. I have tried the answers from here without any luck (it seemed I was already using a properitary driver). Switching between OpenGL software, hardware and hardwarebasic didn't solve the problem.

Anyone with a solution out there?

Setting the JVM to oracle JRE solved the problem for me. Other versions did not work.

export MATLAB_JAVA=/usr/lib/jvm/java-8-oracle/jre

If you are launching from terminal, add the line to your bashrc, if you have a matlab.desktop file, add sh -c "export MATLAB_JAVA=/usr/lib/jvm/java-8-oracle/jre; matlab -desktop;" in the exec field.

Same issue on Ubuntu 16.04 with R2016b. Your solution works for me. Thanks a lot!

The only difference is that I am using Java openjdk from the offical ubuntu repositories instead of Java-8-oracle.

I did the following:

First

sudo apt-get install default-jdk

Second, I added the line

Exec=sh -c "export MATLAB_JAVA=/usr/lib/jvm/java-8-openjdk-amd64/jre; /usr/local/MATLAB/R2016b/bin/matlab -desktop;"

to my MATLAB.desktop file.

I have a similar issue with Ubuntu 18.04 and MATLAB R2016b. When reporting it to Mathworks they suggested reducing the size of the scroll buffer, and suggested I might look at this issue.

These are my notes on how it went, I think I did manage a workaround.

Previously installed Java: I don't think I had manually installed any previous Java. I guess I'm using the Java that came with the MATLAB installation. Checking the output of 'javaclasspath' gives e.g.: /usr/local/MATLAB/R2016b/java/patch

I then installed java as per above, i.e. using:

sudo apt-get install default-jdk

Note: Just starting MATLAB results in the same 'javaclasspath' as before, so it doesn't pick up the Java installation by default.

Using the installed Java (Java 11): Installing the default JDK results in Java 11 rather than Java 8. There's no corresponding 'jre/'-folder at '/usr/lib/jvm/java-11-opendjdk-amd64/jre', so it didn't work to e.g. start MATLAB using:

export MATLAB_JAVA=/usr/lib/jvm/java-11-openjdk-amd64/bin; /usr/local/MATLAB/R2016b/bin/matlab

MATLAB complains about not finding

/usr/lib/jvm/java-11-openjdk-amd64/bin/lib/amd64/server/libjvm.so

which is installed at

/usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so

It's a problem that MATLAB assumes it should add '/amd64/server/' when there's no 'amd64/' folder in the Java 11 installation.

It might be possible to work around this by e.g. adding a soft link in the installation folder.

However, to move on I did:

sudo apt install openjdk-8-jre

The MATLAB desktop IDE now starts using this command

export MATLAB_JAVA=/usr/lib/jvm/java-8-openjdk-amd64/jre; /usr/local/MATLAB/R2016b/bin/matlab

Albeit with the following error message:

PostVMInit failed to initialize com.mathworks.mwswing.MJStartupForDesktop

The desktop configuration was not saved successfully

Anyway, doing a very quick test,

disp( (1:10000)' )

indicates that the graphics is working better now.
