Incorrect formulas

I found a bug not fixed in LO 4.0.1.
Formulas are displayed with errors(some have wrong position, some have an artefacts) and text doesn't seem to be similar as in MSO.

The only, very minor problems observed when compared with Word viewer:
The formula after радиус-векторов has the surrounding r1 and r2 higher than the middle character.
The formula after радиус- векторы is aligned too high.
Word viewer shows the last lines before the line graph as having a much larger line height than LibO.

Formulas in Attachment 76333 [details] are binary OLE objects that can not be edited in Word.
Reporter was supposed to say how document was created, what is formulas source.
I guess for LO they are not "formulas" but WMF images. 
If we open those images in image viewer, they are also not correct.
So I guess we have 2 issues here:
- LO doesn't read binary embeddings
- cached images are not proper
