Win 10 64bit, MSVC2015 U3
Description
Normal rendering, no high DPI scaling involved. Freetype is not affected.
QMessageBox::information(...."<html><head/><body><p>bla <b> bold bla</b> blub" "<i>italic</i>blob</p></body></html>");
Notably shows in Qt Creator 'File changed on disk' dialog.
QLabel(0x270dbf623a0, name="qt_msgboxex_icon_label") "" QFont( "Segoe UI,9,-1,5,50,0,0,0,0,0" ) QLabel(0x270dbf62250, name="qt_msgbox_label") "<html><head/><body><p>bla <b> bold bla</b> blub<i>italic</i>blob</p></body></html>" QFont( "Segoe UI,9,-1,5,50,0,0,0,0,0" )
Appears to be Vista style only. This is then related to the QWindowsVistaStyle::drawPrimitive() drawing a white theme panel on message boxes at src\widgets\styles\qwindowsvistastyle.cpp:788 and caused by some alpha blending issue.
