[ft-devel] FreeType2 2.8.1 with subpixel rendering breaks QtWebEngine

[Mykola Krachkovsky]

Hello,

Updating freetype2 to 2.8.1 with subpixel rendering enabled (uncommented 
#define FT_CONFIG_OPTION_SUBPIXEL_RENDERING) breaks the QtWebEngine. Both 2.8.0 
(and earlier) with subpixel rendering and 2.8.1 without subpixel rendering 
works fine.

Tested on openSUSE x86_64 Tumbleweed. Qt 5.9.1.

It looks like character wrapping left side to the right, but slightly (1px?) 
moved upwards. There are some examples [1] from QupZilla and KMail.
Qt itself (QupZilla and KMail inteface, other Qt apps) and Chromium aren't 
affected and looks fine.
