This has been an issue forever (I have a similar blog post from 4+ years ago tracking down the exact same issue: https://cmetcalfe.ca/blog/diagnosing-periodic-high-ping-time... ) and I can't believe it's still not fixed.

It is fixed, but it requires Qt application developers to update their application to Qt6 or as a workaround they can disable bearer management in Qt5.
