I don't know what is wrong. It could be an issue between Java and the=20
graphics drivers. =F0=9F=A4=94
Or it could be the Java implementation coming from a specific vendor or=20
some settings on your system.

The newest version of Robocode comes with a java2d.bat file (Windows) and=
=20
java2d.sh file (Linux / macOS) that is run when using robocode.bat for=20
running Robocode.
The content of this file looks like this (java2d.bat):

@rem Enable or disable Direct3D acceleration (true/false)

@rem Get detailed information about the startup procedures of the Java 2D=

enable the tracing:

@rem Set the Direct3D rasterizer to one of the following: ref, rgb, hal, or=

tnl
@rem Use ref to use the rasterizer from Microsoft
set J2D_D3D_RASTERIZER=3Dref

Try to adjust these settings. You might also try to add settings for=20
