WinCC OA 3.17 : UlcUx Panel in Browser issue.

[Harish]

I have migrated our project from version 3.15 to 3.17. A UlcUx Panels get loaded in Broswer and Looks fine. But all click actions in panel are freezed. Additionally I could see following messsage in Log Viewer.

"WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed."

Is it a configuration issue? What could it be, that I am missing?

Looking forward for your kind help.

According to information from our developers the log message can be avoided when using the option "--device=software" to start the WCCOAui process. The log message is just an information und does normally not have an impact on the functionality.
Please check if it helps to get rid of the log messages.

Also please check if you have the newest patch 3.17-P005 installed.
