Reproducer

Using the attached reproducer, make the window fullscreen by clicking the window decoration fullscreen button.

Only a portion of the fullscreen window is drawn in orange, while the whole window should be drawn orange.
This can also be reproduced by resizing the window very fast, a small portion of the window is not drawn with the correct color.

This bug does not happen on windows.

Adding a call to redraw() in display() works around the issue.

My guess is that only the previous size of the window is marked as dirty and redrawn by GLCanvas.

I tested 2.4.0-rc-20200306 and the bug is still there

Can't reproduce with (anymore)
com.jogamp.opengl.test.junit.jogl.swt.TestSWTBug643AsyncExec

Tested with SWT 4.26 (as deployed in JOGL for build and testing).

TestSWTBug643AsyncExec does test our GLCanvas as well as NewtCanvasSWT
without animator by default - hence should be comparable.

If the bug still persists please reopen and discuss.
Thank you.
