Looking at Bug 87379 there is a possible regression with Microsoft Equation 3.0 while opening attached sample DOCX.
Some "Omega rSup" signs were correct in LO 4.4.7 and wrong from 5.0 up to 6.2+ as shown in attachment 132807 [details].

DOCX import: convert MathType to Math if MathTypeToMath is enabled
With this, math equations created by Word <= 2003 and embedded to docx
files can be edited finally. Previously the result was read-only and
opened in an unexpected new window.

Sorry, I think this is rather an implementation error than a regression. The MathType <-> Math filter always had this problem, and it was a real bug that this conversion did not happen when the conversion was enabled in the UI.
You can work this around by going to tools -> options -> load/save -> microsoft office -> and untick the load column for math.
(But sure, it's a bug, it would be nice to fix it.)
