So can you confirm that after the fix the next code will work w/o
I am worried since we updated the enumDisplayModes(), but did not update
the getCurrentDisplayMode() which still uses the old code.

Actually it seems that setDisplayMode() should not work since
JDK-8131752. probably someday we should change the code in
X11GraphicsDevice.isDisplayChangeSupported(), which skip the xinerama case.
