question: private static void enableOpenGLIfNecessary ( ) { if ( OperatingSystemDetector . isMac ( ) ) { Log . i ( "Enabling OpenGL." ) ; System . setProperty ( "sun.java2d.opengl" , "True" ) ; } else { Log . i ( "Not using OpenGL." ) ; } }
target:  We only use OpenGL on OS X, because it caused lots of bugs on Windows and performance issues on Linux. Also, this is the behavior of Amidst v3.7. On Windows Direct3D is better supported and the default. Linux has accelerated images without activating OpenGL. The reason for this is still unknown to the developers of Amidst. https://github.com/toolbox4minecraft/amidst/pull/94
