A user complained that after his upgrade to Windows 10, the rendering of some characters in Paratext 7.4 did not look right. Specifically, when an “i” had a diacritic over it, the display showed the diacritic overlapping with the dot over the “i”, when before the upgrade, the sequence displayed as a diacritic over an i without a dot.
When I suggested that he try the alternative rendering engine, that fixed the problem.
The problem also appears in 7.5, if the alternative rendering engine is turned off.
