According to the computer specifications, the graphics is 2nd generation, the latest graphics driver is version 22.214.171.12415, and I do not have similar issues reported with that graphics driver version.
Try testing an earlier version
Or check with Siemens to see if there are customized drivers for your computer model.
Earlier driver does not help.
The soution was to disable the graphic-acceleration in windows.
Can be found here (for XP)
Rightlick on desktop
+ Tab: "Settings" (Einstellungen)
+ Tab: "Advanced" (Erweitert)
+ Tab: "Troubleshooting" (Problembehandlung)
+ Slider Hardwarebeschleunigung: auf „Keine“
I think there are a lot of issues with this driver as there are also a lot of problems when using office as i saw in other threads here.
