Checking responsiveness for print dialogue of KDE editors

I would like to try a specific functionality out in programs like Kate and KWrite (version 17.12.2-1.1). So I pressed the shortcut “Ctrl+P”.
It takes an unexpected long time until the print dialogue is completely displayed (and is finally usable) here at the moment. I find such a responsiveness issue strange.

The expected print settings are immediately displayed by other text editors.

Do you observe also any significant differences in the software behaviour?

I wonder still about the time it can take to show the print dialogue by programs like Kate and KWrite (version 18.04.2-2.1).

If I check the program execution by a tool like “strace”, it seems that a function call like the following can have a significant influence.

statx(AT_FDCWD, "/home/elfring/.…", AT_STATX_SYNC_AS_STAT, STATX_ALL, …) = -1 ENODEV (No such device)

Would you like to share any further ideas to improve the software behaviour?
