GTT GUI Issues

 

Issue Title Description Potential Solution
GTT Crashes while launching streaming window. Performance counters cannot be accessed while starting streaming. One of the reason, GTT may crash while starting streaming could be the Performance Counters are not properly initialized or they are corrupted. This could be solved by rebuilding the performance counters.

To rebuild all Performance counters including extensible and third-party counters, type the following commands at an Administrative command prompt. Press ENTER after each command.

Rebuilding the counters:
cd c:\windows\system32
lodctr /R
cd c:\windows\sysWOW64
lodctr /R

Resyncing the counters with Windows Management Instrumentation (WMI):
WINMGMT.EXE /RESYNCPERF

Workaround for LUT parameter sets unit problem[Backward compatibility]

This issue will happen with every single LUT object in every set group with this device file. What seems to happen is the panel is appending the unit of each parameter into the set file, which is corrupting it.

This workaround required for projects which are exported earlier than N+1 release.

  • Import earlier exported project.
  • Open Signal Flow designer , if all LUT objects belong to same group, launch panel by double clicking any LUT object.
  • If  each LUT objects belongs to  different groups. Launch panels separately for each group.
  • Close opened LUT panels.
  • Open Parameter sets view , right click on column header of red color highlighted set and click ‘Store’  context menu to get latest set values.

You can observe red highlights are cleared and units are removed for each state variable.
