is it a bug in opera GX? when the same file works on normal opera

@lande91 Tested the same custom animated theme on normal opera and it works. but not on opera GX.. hmm

@leocg My webm was 63mb and the limit is 50mb. so close,
after reducing the size to 13mb and a length of 15sec it still does not work. I use Winrar to make a .zip file, the files are named video.webm, persona.ini, first_frame_start_page.jpeg, have tried with and without a folder and i use the easy setup to choose a zip file from "add your wallpaper"

ini file :

[Info]
name = test
author = raudlauk
author url =
version = 2

[Start Page]
background = video.webm
position = center bottom
first frame image = first_frame_start_page.jpeg

Re: installing custom theme

I can't seem to get custom Animated background to work using zip file Opera gx version: (LVL3 (core: 77.0.4054.298).

i have added the files to a folder and have remade the ini files many times with different configs. is there a size limit on the webm? or length limit? There is sound in the webm i am testing, does it matter?
