Can you give feedback like a normal human being?
What, you think Unity’s executives are having a daily meeting where they discuss how they’re gonna make the engine worse? “Aright guys I’ve come up with a new idea. Let’s make the engine repaint every 2 seconds, that’ll show em”
No one over Unity is trying to make the engine unusable, it’s obviously a bug (which is ok to have since this is a beta version).
If you want to help Unity solve this instead of throwing a tantrum then fill a bug report, attach an editor log, profiler log, and possibly also a project where this can be reproduced.
Sure it’s just yet another bug, but constantly introducing new bugs when fixing bugs signals “management doesn’t care about clean code nor about good coverage by automated testing”.
