webMethods Designer GUI Blink Sometimes

Hi, currently i using webMethods Service Designer 10.15 Free Trial with IS Embedded.

Why sometimes after i do some activity like debugging or run flow service and etc, Service Designer is always blink one ore two times?
Is it correspond with Full GC that cause JVM stop the world?

Is any log that i can to provide? If there is, where can i get?

I have seen something similar in 10.15: Designer will lose focus and I will need to switch back to the window.

But your issue sounds like it may be related to this Designer fix ESB_10.15_Fix4:

At times, Designer 10.15 does not display pipeline contents instantly.

During flow service development or debugging, Designer displays the pipeline
contents for an element with a slight delay of one second or less. Typically,
the delay occurs when the pipeline has multiple document references and
transformers in the mappings.

This issue is now resolved. "

I don’t know if the free trial version includes fixes

Right, that’s i means.

I think it fixes had applied for free trial version sir.
