@khandakershahi and @pheiduck I notice you’re both using AMD GPUs. This is very likely due to the change in mesa. 
@MirceaKitsune even with a 4K video in YouTube (watching it at the maximum resolution), you’re still not seeing any extra CPU usage or temperatures? Even if you let the video play for a while?
I have a problem with xfce screenshooter after this update.
I am trying to take a screenshot of a selected area of the top application window but it is ignoring the application windows and only seeing the wallpaper on my desktop.
I’ve reinstalled screenshooter and tried taking screen shots of different application windows but it only seems to see the desktop wallpaper.
Is anyone else experiencing this odd behaviour?
Plasma freezes will NEVER be fixed 
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”.
AMD CPU usage and temperature:
AMD GPU usage and temperature:
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
Here some information

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.
