#### Fixed bugs
- Windows: Fixed repaint issues (ghosting) on some systems (probably depending
on graphics card/driver). This is done by setting Java system property
`sun.java2d.d3d.onscreen` to `false` (but only if `sun.java2d.d3d.onscreen`,
`sun.java2d.d3d` and `sun.java2d.noddraw` are not yet set), which disables
usage of Windows Direct3D (DirectX) onscreen surfaces. Component rendering
still uses Direct3D. (issue #887)
- FlatLaf window decorations on Windows: Fixed possible application freeze when
using custom component that overrides `Component.contains(int x, int y)` and
invokes `SwingUtilities.convertPoint()` (or similar) from the overridden

/**
* 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.
*
