When I create a GLCanvas with a GLCapabilties with setStereo(true), Swing
controls don't seem to all work properly. Some of them (e.g. buttons) work
fine, but others only change the output to the left buffer of the graphics card.
For example, a JTextBox, when generated, shows the default text in both the
GL_LEFT and the GL_RIGHT buffer, but if the text is changed, only the GL_LEFT
buffer is updated.This problem also "spreads" to other Swing components if the
GLCanvas is dragged around the screen to conver and later uncovers them - after
this, only the GL_LEFT buffer is updated.
