3.18 P012: Softpanel loads but shapes are invisible

[emaddocks]

We're upgrading to WinCC OA v3.18 P012 from P004 on RHEL 8.2.

We are using the Stdlib_3.18 hook functions for 3.18, carried over from 3.17 and they were working fine in 3.18 P004.

However now in 3.18 P012 when we load a devices panel into the softpanel module it only works the first time. If you load the panel again into the softpanel it loads but all it's shapes are 'invisible'. By 'invisible' I mean that you can't see them but the mouse can. So you can still click on shapes when the cursor changes to a hand and the scripts run fine.

If you load an empty panel into the softpanel module in between each device panel selection the devices panels work every time.

Nothing comes up in the log viewer to suggest something is broken as I believe OA thinks the panel has loaded fine...just not visible to the user...so maybe this is a OA interface with qt bug??

Has anyone else seen issues with the Stdlib_3.18 project since upgrading to P012?

Can you please desribe in detail what a "softpanel" is.
If the problem still persists (when using the newest patch 3.18 P014) and you need further assistance please get in contact with your common WinCC OA support.
