Weird problem with web-video

If I open any video with firefox, squares appear on the edges of red or orange objects. I tried to open videos in Chrome and the issue didn’t appear. But I don’t want to use chrome, because it is much, much slower than firefox plus it has almost no really advanced settings.

:+1: Welcome to Manjaro! :+1:

Please read this:

and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

:+1:

Here is it:

inxi --admin --verbosity=7 --filter --no-host --width

As you have a GeForce GTX 480 the 390 series nVidia is indeed the correct one.
