> Both our source code and the command use the same property, _NET_WORKAREA. When I noticed the issue, I thought that maybe we are misusing the _NET_WORKAREA in getScreenInsetsImpl(). However, as you can see in the traces in [JDK-8357390](https://bugs.openjdk.org/browse/JDK-8357390) , it returns the same values as the xprop command does.

@anass-baya You mentioned previously that the difference might be related to window manager. Which window manager is used in the 2 cases (the one where the test passes vs fails) ?
