When using large font size (200) in Qt Quick 2 TextInput or Text element text for component is completely misplaced in screen (see attachment picture). NOTE: Qt needs to be configure+build without fontconfig support.
Commenting out following lines (from file src/gui/text/qfontengine_ft.cpp) in function QFontEngineFT::loadGlyphFor does fix the issue:
if (glyphSet != 0 && glyphSet->outline_drawing)
Change c238d34137ffe80d30933733a12aa2893b9631c2 did introduce this problem.
