@leocg I am also using opera Gx on another device but it is not happening on the opther one. I retried restore the setting but still it is reseting the animation.

The speed dial auto refresh when ever I click on it. How can I disable it. I have a live wallpaper and it resets everytime I click on speed dial.

@shialee You need to convert the video into webm. Take the image of first frame for thumbnail. Take the file persona.ini from any installed theme you have and edit it as shown in the screen shot. edit the background= to match the name of the video file and first frame image to the name of the image.

take any theme file. Delete its content and put your files in it.

If there is any problem feel free to ask me.
