QWebEngineView not align properly in certain PC

[hghew]

I build a QtApplication using QWebEngineView in MSVC 2015, i open the QtApplication in multiple PC , somehow one of the PC show misaligned of QWebEngineView, many others PC do not have this problem, only one of the PC (this PC does not have any Qt development kit install), i tested on other PC with/without Qt development kit install, seems okay.

Any idea? or something missing regarding the web settings? thanks.
