I also saw that behavior on windows and on linux I observed flaky behavior of the terminal and this is matched by exceptions:

{quote}SEVERE [global]

	at java.desktop/javax.swing.JComponent.paint(JComponent.java:1083){quote}

So we either need a quick fix for this or we need to rollback the referenced commit.
