(9735) Radeon 7500 GKS Display Error?

[User]

We are moving our GKS (Ver. 6.5) applications from AlphaStation 255/233 to
AlphaServer DS10. Static GKS screens display correctly on the DS10.
Dynamically refreshed screens do not. Specifically, one screen consists of a
static background graphics overlaye
d with periodically (every 10 sec)refreshed dynamic graphics. Most (but not
all) dynamic graphics appear only for a split second when the screen is
brought to the foreground. This screen displayed correctly on the AS 255/233.
The AS 255/233 has the PBXGB-
AA Power Storm Graphic Board. The DS10 has the Radeon 7500 Graphic Board. When
I plugged in the PBXGB-AA board into the DS10 our dynamic displays worked
fine. This suggests GKS/Radeon 7500 compatibility problem. Is there a solution?
We are running OpenVMS 7.3-2 with VMS732_UPDATE-V0200 kit installed.
