Italic text is cut when QSGRendererInterface::Software is used

Italic text is cut in the end of line when the text wraps to next line. See the attached screenshot (italic.png). This happens only when QSGRendererInterface::Software backend is used.

The attached example can be used to reproduce. Resize the window such that it wraps at the end of a word. Characters r and d are best for observing.

Adding padding or margins doesn't help, but font.letterSpacing does.
