[gradsusr] save unders in RHEL6

[Dan Schwarzkopf]

when GFDL went to RHEL6 for linux OS, we lost the save-unders feature
on the X server. This has the consequence that on our version of GrADS
(both 1.9b4 and 2.0.a7.oga.3) when the graphical window is minimized,
then brought up, the screen is blank. (Same when the window is moved
from one desktop to another, but not when another application overlaps
the GrADS  window, temporarily).
1) is there a newer version that solves this problem?
2) if not, are there plans to fix this problem?
