Dear Maintainer,
java.awt.Robot fails to capture the screen if wayland is used. (which is the
default in Debian Buster)
Code to reproduce:
public void captureScreen() throws AWTException {
Robot robot = new
Robot(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice());
BufferedImage screen = robot.createScreenCapture(new
Rectangle(getDefaultToolkit().getScreenSize()));
try {
ImageIO.write(screen, "jpg", new File("/tmp/screenshot.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
}
Or install the remote desktop tool from
https://github.com/RetGal/Dayon/releases/download/v1.9.1/dayon_1.9.1_all.deb
and run both, assistant and assisted on the same system running Debian Buster
with default Gnome-Wayland desktop.
The same code works as soon either Oracle JDK or Xorg.X11 is used.
I already addressed this issue to the Wayland developpers, here is what they
said:
This is not a Wayland bug, this is a problem with java.awt.Robot. Report it to
the proper place. Let them know that they can take screenshots with dbus or
with wlr-screencopy, depending on the wayland compositor in question.
