I installed the newest ubuntu desktop on dell Inspiron 14 7440, and when I open a video (either mp4 or webm) with GNOME videos it looks like this in the image, showing horizontal bars.
Is this a graphics driver problem? I haven’t installed any kind of driver after the ubuntu installation, and if it is a driver problem from where should I install the driver?
You must log in or # to comment.
Have you tried any other video playing application to see if the problem persists?
