I have several graphics instabilities and issues using Matlab 2016b on Ubuntu 16.10 with an Intel 520 (Skylake) graphic card. With hardware graphics, Matlab hangs without any error message when I plot something or try to quit it. Both with hardware and softwareopengl graphics, when I type command whose output exceeds the current window size the background becomes grey (from the original white) and artifacts show up (such as past contents of the window superimposed with its current content). "Clear command window" restores a clean view, but Matlab is still very far from being usable.
I have installed the Ubuntu package matlab-support, but it didn't help. My java version is java-8-openjdk-amd64. "opengl info" returns the following.
Error using hgopengl
Java exception occurred:
java.lang.RuntimeException: Waited 5000ms for: <4973eff0, 5a8d9b3c>[count 2 [ add. 0, orig 2], qsz 0, owner <Startup Class Loader>, add.owner Startup Class

Error in hgopengl
Are there known issues with this platform? Is there a workaround?

Nope. It's still there with 2017b. I have to resort to "clear command window" periodically after a certain amount of output text.
