Let this video play for at least 5 to 10 minutes, longer if possible.
(Open it in YouTube’s website, not in here!)
Preferably in fullscreen, or at least in “theater mode”.
Do not let it “auto-select” the resolution.
Select the 4K 60fps option (which is the highest resolution and framerate to choose from in the viewing options.)
Keep an eye on CPU temperatures (all cores and/or composite) throughout.
Keep an eye on CPU usage (all cores and/or composite) throughout.
Repeat the same exact thing after applying the Stable Updates and rebooting.
(Make sure to view the video in the same exact way before and after.)
UPDATE: See my post further down. @Begemoth made a good point, in which YouTube videos are unlike to be AVC or HEVC anymore, as they shifted towards more open video codecs now.
You have 16 cores, what do you expect will happen?
@winnie I don’t think 4K plays even now. Will see when i have time for that sh**. I hoped there’s some benchmark I could do, instead of using my eyes and feelings.
Tested it on Firefox for a few minutes: Roughly 15% - 20% CPU usage, max 25% reached at times only during fullscreen… temp can get to 60 C*, usual idle temperature is 45 C* with the CPU normally exceeding 80 C* at 100% use. I’m also on 16 cores, no overclock so it runs at the default 3.6 GHz to 4.4 GHz.
Thing is that seems exactly like what I’ve always noticed. I didn’t check CPU usage thoroughly when watching Youtube in the past, but whenever I looked at CPU usage during 1080p played at 2x speed it was about 5%, exact same behavior I’m seeing right now. So I presume whatever got disabled now has always been turned off in some way at least on my hardware.
My problems with nvidia hybrid not detecting external monitors didn’t get fixed with the update. I deleted manjaro on 3 machines, bought a desktop to escape this nightmare. Best of luck Manjaro team, it’s been a wonderful 7 years (and I mean that). You made me believe in the linux desktop, the KDE spin was masterful and well maintained. Was.
Here is a more accurate test, based on what @Begemoth corrected me on. (Because YouTube videos don’t necessarily use AVC or HEVC, as they are shifting towards more open codecs. Hence, YouTube videos are not good tests.)

The video is nearly 1GB in size, but it’s a high bitrate and resolution, and uses HEVC. It will be a good test on whether or not your GPU is using hardware-accelerated decoding.
A better test would be with a 4K video, but the size would be very large.
Here’s a 4K video that is 3 GB if you want to really give this a proper test:
well, it still is you just need a distro that hasn’t disabled the feature or compile it where it has. And so far as compiling Manjaro is probably one of the easiest.
I was getting an issue with window positioning in kwin wayland. The window rules did not work. Deleting old rules and creating them again solved the issue
Not gonna spend that much time on it, was just curious to test it to some extent. Did the first one in both VLC and Dragon Player: Only between 5% and 10% CPU usage, so basically same as Youtube in Firefox.
