Blurred user interface buttons in MacOS

Problem:

I am using Flowable Designer for Collibra workflows. I have MacOS Big Sur 16.8. When I create a diagram and try to connect its elements, the buttons in the UI are getting more and more blurry.

System

“java version ‘18.0.2.1’ 2022-08-18”
I have macOS Big Sur 11.6.8


Did anyone encounter the issue?
