Fullscreen java apps not displaying properly

[bedfojo]

I run a java app (work remote desktop). When run as full screen, it does not go full screen properly - as the MATE panel remains visible.

This is a regression in Ubuntu MATE 16.04. In MATE 15.10 the problem did not occur when running Marco as WM (but did occur when running Compiz).

It is likely a regression from an old issue with icedtea hardcoding certain window managers.

What window managers exhibit this behaviour and which do not? And what is the Java application?

The java application is HOBLink JWT (http://www.hobsoft.com/products/connect/jwt.jsp) which is a remote desktop client which I use for access to my office network.

In 16.04, all window managers show this problem. In previous Ububtu MATE versions, only compiz had this problem: when using marco it did not occur (I would use MATE Tweak to swap when using the java app). Hence the regression issue. I am not sure if it is in MATE or in icedtea.

I can fix this problem in compiz by installing Compiz Config Settings Manager and under Utility -> Workarounds checking the box "Legacy Fullscreen Support". The app then goes fullscreen without the MATE panel being visible.

As you have found a work around and running Java application for browser plugins is being phased out this is not something we will be working to fix. Sorry.
