Hello,
I installed OpenJDK which worked fine apart from being very slow, so I decided to install Oracle's JDK to speed things up.
I uninstalled OpenJDK then installed Oracle's JDK (ARM) from the official site, this caused the GUI of the java programs to look very distorted with no text. I then installed the Oracle JDK (ARM) from the AUR, which has the exact same effect.
Here are some screenshots:

Does anyone know whats going on?
