800xa graphic display value freezes
My system is 5.1 rev.B. Operators work in windows mode.
We have one operator workstation with three monitors and on one of monitors dynamic process values are frozen (not updated), but if you drag that window to another monitor all values are updated and if you drag it back is displayed old values.
We usually reopen that window or sometimes restarting the computer and for some period it's okay.

Sounds like a bug in .NET / WPF.
I assume graphics is made in PG2.
With PG2 the workplace has little or nothing to do with the painting; this is carried out via Windows Presentation Foundation (and .NET) which a kind of "black box" feature of Microsoft Windows where little of the internals is known by ABB.
Ensure the *mandatory* .NET hotfix is installed, originally called KB967634 but later superseeded by KB2667241
Sometimes problems can be abated by:
- Changing from Windows Classic to Windows Aero theme
- Disabling Hardware Acceleration on graphics driver*
- Changing to another graphics accelerator and device driver
*) If driver settings does not permit disabling of hardware acceleration, you can use a registry key to do the same. Further details are to be found in this article: https://msdn.microsoft.com/en-us/library/aa970912(v=vs.100).aspx
Also, some additional protection against WPF problems has been added in later revisions of 800xA (e.g. 800xASYS-OL-5103-003) please refer to the release notes for additional information: 2PAA114364-510
Ultimately, have a support case logged with your regional ABB support center.
There is one known field alert for 5.1 revc/fp4 no idea if it applicable to this as well.
