I have also been experiencing all the issues you note since SU14 was released. Thankfully a restart of the flight or a switch in and out of VR seems to resolve them, but it is still a bit disappointing that such simple UI issues exist in the first place.
I too used to participate in the SU betas, but gave up in frustration at a IMO notable VR bug I reported back around 18 months ago (Cursor focal point misaligned in instrument views) that is STILL not fixed. VR users may be a minority, but that shouldn’t mean we get ignored entirely.
