Try:
There is a registry entry you can set to disable
fast double-buffering; when this is set to 1, your
app's gui works correctly. The path in the registry
for this entry is
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/glint/Device0
Add a new DWORD value called DoubleBuffer.DisablePageFlip;
set this value to 1. You do not need to reboot or log off.
Start your app and it should behave correctly. There is a
performance penalty for this mechanism, so it should be
considered a temporary work around.
Please let me know if it works or not
