LO 3.6.4.3, Windows 8. LO Math has default settings like fonts and spacing.

Formulas “2 cdot 3 = 6” and “sqrt {16} = 4” looks like

The “cdot” is selected in editor and you can see it’s bounding box. But the dot symbol is outside this box. Also the root symbol is torn.

How to fix it? I had not such problems on Windows 7.
