I know I could use insertPlainText() which does not add a new line character but it uses a lot more memory when de...
I have a simple Qt application that launches a window with a QWebView. I tried several sites using the video tag with h.264, and it either can't play the video at all (as in youtube or sublime video), or it renders the video poorly, with black lines covering parts of it, like when viewing the video here.
