Am I the only one whose installation effectively crashes because it cannot download linux 6 headers? How do I convince pamac to try a different mirror after it fails to complete a download after 12 hours?
I have no issue with AMD GPU and mesa 22.2.4. 
Firefox runs fine with 4k Youtube when using default hardware acceleration. No high temperature, less than 10% GPU usage and CPU usage.

Hm, I have a bug with qemu, my vms won’t boot
Seems a Kernel bug, because downgrade of qemu does not change the behavior
Fixed:
I have 2 core amd laptop with amd igpu. If you have any tests in mind I can do them before and after update.
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.
Longer than 10 minutes in fullscreen then “theater mode”.

Do you know if this was the same before the mesa update?
I think it’s the same as before.
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.
When I turned off hardware acceleration in Firefox. See the CPU usage is high when playing 4K video.
I think that is normal.
@khandakershahi has the issue, because hardware acceleration would not work or disabled in Firefox.
get this: 5.15.81
==> WARNING: Possibly missing firmware for module: ast
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.
Plasma sitll freezes randomly 
I’m lost: no sound in google chrome or firefox but sound with clementine. I have no idea what to do and return to an backup of 4.12.22

This Manjaro is useless without sound in browser!
For Manjaro, you mean?))
This is have no sence since YT uses VP9-AV1 codecs for the most of the times, but for 4k — always. H264 codec Youtube uses extremely rare.
There will be problems with other platforms (Twitch, for example) and the most offline videos.
We can still use mesa-git from AUR, h264-265 didn’t drop out there.
But still this is a shame, I don’t see any reasons for EU distro to drop h264-h265.

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.)
Let this video play for at least 5 to 10 minutes, longer if possible.
Preferably in fullscreen.
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.
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:

Not just CPU temps and usage, but also how “smoothly” does it play?
Little correction: h265 isn’t supported by browsers, just not able to play that codec.
We can use vainfo (terminal command), it shows which codecs you can accelerate and by what. That is mine, for example, with mesa-git:
If you have AMD graphics and mesa from Manjaro repo, you will see output from this post.

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.
