Ok, I actually downloaded java version 151 from https://java.com/en/download/mac_download.jsp and I confirm that the problem went away. I think that for me this fix is good enough, thanks
We’ve been able to reproduce the issue. It seems you need to adjust the width and height of the Console panel at least once for it to draw properly. We store this in the preferences file, so the next time the editor is restarted the Console is “resized” without you having to do anything. Thus it appears the issue is fixed the next time you start, but if you somehow delete the preferences the issue will probably reappear. We need to grab the initial width and height and not rely on a resize event.
Thanks to everyone who posted and helped us figure this out! We will have a fix merged shortly. In the meantime if you have this issue, try adjusting the dividers around the console panel so both the width and height is adjusted. Hopefully that should get the text back.
