Part & assembly freezing issue with Creo 8

[prabb]

Hello,

I have a weird freezing issue with Creo 8.0.7. I am using a notebook with a dock and when I have to disconnect and connect the notebook during the day, the Creo kind of freezes.

The weird thing is that Creo works normally, but only the part, assembly or drawing window totally freezes. I cannot modify, zoom, pan, rotate - nothing.

To fix the issue, I have to restart Creo. Luckily all the Creo functions works, so I have possibility to save the work. But restart the Creo with every dock reconnection is annoying.

Could this be hardware (dock) issue? It is a Lenovo AF40 USB-C hybrid dock. There is no similar problems with other programs, like Autocad or Windows office programs.

Same issue - "Creo 8.0 freezes and un freezes every two seconds": https://community.ptc.com/t5/3D-Part-Assembly-Design/Creo-8-0-freezes-and-un-freezes-every-two-seconds/td-p/837151

Thank you.

But it is not the same problem. My freezing issue seems to be related when connecting to a dock. If I don't dis-/reconnect to the dock, the Creo works fine. And in my case, the Creo window freezes completely, until restart. Only the toolbar-icons work.

The Creo however works when using it on the notebook screen. There seems to be no logic, why it freezes with dock/external display.

It looks like opengl driver issue,

Try to reinstall/upgrade/downgrade video drivers

Try to upgrade Creo to 8.0.12.0

And check the issue with Creo config option

enable_opengl_fbo no
