Thankyou for trying. Where did you get 6.3 ? I can't find it on the libreoffice website.

For temporarly erasing the effects of the bug, type = at the end of the line and erase it again. There has to be no space between the last part of the formular and the =.

I tried to write with my class formulae and it did NOT vanish when re-opening. It was a full desaster. 

But it was an older LO version (6.1.???) - have to check in school. Win10.
Also closing and opening document did NOT help. 

It was really strange: 
ALL 15(!) or nearly all pupils had these problems.
15 Children complaining at once. 
All the formulae were in the mid of document. 
"Objects" and below: "How to write a formula". 

I tried in the document - NO way. E.G. a square root became 10cm in height.
(It was an "example" - check out).  It was not only overlapping. 

After that disastrous hour I logged in with my DummyUser account- typing formula- everything perfect! No way to reproduce. This was at the same computer where I had before these huge problems where I tried to fix the problem in the document of this 16 year old pupil and I failed.

and it looks fine, I think it's WFM now

Patrick, if you still have the problem, then feel free to reopen the bug report, thanks.
