Wyse S10 6.5.0_30 graphic performance slow

Hi,

for testing I upgraded the firmware from 6.3.0_22 to 6.5.0_30 and noticed that the graphic performance (for example scrolling in IE8) on Citrix PS4.0 is slower. Also with Office 2003 I have the same behavior.
Tried to change display colors (16 to 32bit) and also the option “speedbrowser=on” without success.

Maybe someone else has the same problems and can give me some advice?

the wnos.ini and user.ini looks like this:

wnons.ini

#Enable sign-on process
signon=1

#Default signo-on user = PC-Name
Defaultuser=$TN

#Bitmap filename displayed in the sing-on window
