Description
When code from themes set font it calls QFont::exactMatch(). But I've found, that function always return false, even if the font available. This is output from debugger in QFontDef::exactMatch(), that is called by exactMatch() when Material theme is used:

Though fonts are found, some parameters mismatch: pixelSize, pointSize and ignorePitch. I don't know, is it a bug in Qt font system or exactMatch() shouldn't be used this way.
On my system I have no font installed system-wide, I loaded the font using QFontDatabase::addApplicationFontFromData(), but this may be reproducible when font installed into system too.
