There are some rare instances when the process panel goes blank in RapidMiner 9.x. This is an acknowledged bug and the engineering team is aware of it. Meanwhile if you encounter this type of occurrence, we recommend simply using the "Restore Default View" feature to fix this:

Quick fix: go to View -> Restore Default View
Thanks all for reporting this so quickly!

@sgenzer, do you mind to run java -version on a Terminal window? It happens to me when I have JDK 10 in my $JAVA_HOME, but couldn't reproduce it on Java 8. I'm using it a lot, so I wouldn't venture to switch JDK's.
(Besides, there have been some changes on Swing/AWT in Java, AFAIK).
so interestingly enough I just updated my Java yesterday after postponing for a while. Right now I'm on
1.8.0_144-b01. But you should really sync up with @Marco_Boeck as he's the engineering lead.
THANK YOU Rodrigo!

Hi,
Nope, this problem unfortunately affects also Java 8. We have identified yet another possible cause for it and are looking into preventing it from happening. But thank you for your idea, much appreciated!
(But I'm already looking forward to all the fun problems that upgrading to Java 11 will cause at some point in the future...
)
Regards,
Marco
This has been fixed in RM 9.0.2. Please update to this version once it is released.
