 To switch to the newer QtWebEngine web backend, add this section to the
 ~/.config/otter/otter.conf:
 
 [Backends]
 Web=qtwebengine

+If you get wrong colors when watching videos while using the QtWebEngine
+backend, this is probably because your system does not support hardware
+acceleration (see bug 237277): you can disable it by starting the browser
+from command line with the --disable-gpu option.
