Bug Description

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?

Changed in ubuntu-mate:
status: New → Incomplete

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.
