    inverted images are usually a cause of an incompatible driver.  you may want to see if there is an update for your video card.


    if you'd like to follow the example above, open the terminal/konsole app and type what you see above followed by the browser app you plan to use.  i'm not suggesting you do so but the command would look like this:


    export LIBV4LCONTROL_FLAGS=3 && LD_PRELOAD=/usr/lib64/libv4l/ firefox
