Hi!
What happens in the terminal when you type bluej there and enter?
(java:201309): Gdk-WARNING **: 08:16:34.598: XSetErrorHandler() called with a GDK error trap pushed. Don’t do that.
ok… same for me… did you agree to the window that you are over 16 years old?
i never got a window to agree to anything, i just simply launched the program
There must be one. Maybe it is behind a window or in the second screen 
Somewhere hidden?
it’s right here ahaha it’s so broken
Yeah 
Seems Plasma failed to read the correct resolution of the window. You could try to expand it with your mouse.
Maybe try the flathub package… could work better.
expanding doesn’t work cause theirs nothing to expand it ahah
flatpak (flathub) doesn’t seem to work either
I guess bluej is made with GTK and not QT, which is common in plasma. I guess there is an issue. On XFCE i have no problems with that.
yeah I can replicate same error on 5.4.60-2-MANJARO, with Plasma 5.19.4. Anyone got an idea how to get pass the 16year popup?
I’d like to stick to Manjaro and plasma. Any suggestions?
Just found an ad-hoc solution now, when starting up BlueJ you will get the BlueJ main window and
the small x11 window that is the wrongly drawn 16-year popup.
Hover over the almost invisible popup (focus through taskbar first) and click in the middle of the x11 window (will get a little bit wider). Then just hit on your keyboard, and voilà the popup is confirmed and gone.
GG for the trick! Thanks 
no worries, in the meantime I realised this is only a partial workaround as the prompt might occur again:
see this post here:
and download bluej .jar file here to get blueJ installed properly:
