public static void disableWindowsD3Donscreen() {
		// dummy method used to trigger invocation of "static {...}" block
	}
Disable usage of Windows Direct3D (DirectX) onscreen surfaces because this may lead to
repaint issues (ghosting) on some systems (probably depending on graphics card/driver).
Problem occurs usually when a small heavy-weight popup window (menu, combobox, tooltip) is shown.
<p>
Sets system property {@code sun.java2d.d3d.onscreen} to {@code false},
but only if {@code sun.java2d.d3d.onscreen}, {@code sun.java2d.d3d}
and {@code sun.java2d.noddraw} are not yet set.
<p>
<strong>Note</strong>: Must be invoked very early before the graphics environment is created.
<p>
This method is automatically invoked when loading this class,
which is usually before the graphics environment is created.
E.g. when doing {@code FlatLightLaf.setup()} or
{@code UIManager.setLookAndFeel( "com.formdev.flatlaf.FlatLightLaf" )}.
<p>
However, it may be invoked too late if you use some methods from {@link UIManager}
of {@link GraphicsEnvironment} before setting look and feel.
E.g. {@link UIManager#put(Object, Object)}.
In that case invoke this method yourself very early.
<p>
<strong>Tip</strong>: How to find out when the graphics environment is created?
Set a breakpoint at constructor of class {@link GraphicsEnvironment} and look at the stack.
