I know that post was written a few years ago. Mike J, I have a similar issue.

I also have a MAIN screen with two picture windows: one picture window for each monitor.

I also have in picture window for monitor, one picture window for the menu/navigation.

My screen has an OnlineTrendControl and a RulerControl, and it opens very slowly.

How did you resolve this problem?

Or does someone else have a similar problem?

Split from Trend Window slows down picture opening.

When they are on screen (if visible or not), on screen load they load the data and this can take some time.

If you don't need them always visible, put the trends in separate PDL and show them in a picture window in your main PDL. Then the main screen itself is fast loaded when the picture window is set to invisible. If you need them, press some button to set picture window visible  - but then there will also be some loading time

Thanks for your answer.

Is that a normal situation in WinCC, to wait a few seconds for the trends screen to open?

This is my first project in WinCC, so I don't have much experience.
