--- Comment #41 from lattro...@yahoo.com ---
I have the same issue as described in the initial post, obviously with
different timestamps. My SOFTWARE/OS VERSIONS are all different and listed
later.

The only differences are that I do not have "KWIN_DRM_DEVICES" set, I have 1
dedicated GPU an integrated one and I do not have anything installed that uses
chromium.
--
Like Comment #12, I get the same symptoms except it's reddit and youtube. Have
not tested anything with powerdevil yet.
--
Like Comment #15, I have seen the same journal entries as shown sans
timestamps. They stand out because I recall I searched a dictionary for
quiesced and quiescing, trying to understand the context and the results gave
me a recipe for quiché. This probably has nothing to do with quiché. I can post
my logs if needed but I have another unrelated issue spamming my logs a lot.
--
Regarding Comment #25 my lockups happen for 25 seconds. 

After the lockup is over, if I bring up my Yakuake terminal, there sometimes is
621 empty prompts, as if I had hit Enter/Return 621 times, without entering any
command. That seems like it is not a coincidence. I never have seen
"kwin_wayland_wrapper[1368]: Key repeat discarded, Wayland compositor doesn't
seem to be processing events fast enough!".

I am using 2 Displayport and 1 HDMI ports currently. Another Displayport and
the iGPU HDMI are unused. One of the Displayport cables is a Displayport to
HDMI cable.

Mentioning the previous, since I saw ddcutil in a journal entry in a comment,
which is for monitor control and it interacts with powerdevil. Reading about it
leads me to believe the issue might be with code that interacts with
powerdevil, specifically with monitors, like vdu_controls or ddcutil-service.

Comment #27 I'm partially experiencing, middle clicking works fine on some
pages, including this one as I started typing this.

If I middle click on links, images or videos it opens them as expected without
freezing. I can middle click tabs which close as expected without any freezing.
Middle clicking non-link text or empty space always causes the lag/freeze to
happen.
--
Comment #30 If I hover over a youtube thumbnail, it plays the preview as
expected, no freezing. If I do that, then hover over another thumbnail, I get
the freeze.

Thoughts/additional info:

I have not tried the Powerdevil workaround yet. My power saving settings are to
power off monitors after 90 minutes, then go to sleep 90 minutes after that
(180 minutes no activity) and the freezes occur without the computer going to
sleep.

I started my computer after having it shut off for hours to clean the case. I
checked Firefox immediately after logging in and connecting to my neighbors
wifi (with permission) and the freezing issue occurred with a middle click. So
it occurs regardless of whether the power savings/sleep/hibernate/suspend
settings activate or not, for my system.

Maybe it has to do with the monitors themselves? Perhaps a brand/model has
weird/bad EDID settings or other irregularities? 

I have a lot of monitors and I switch them around occasionally, most (but not
all) are 10-20 years old. In particular, an Asus monitor (VP249) has given me
problems. In kinfocenter I see that particular ASUS monitor has a failure:

"Display Range Limits: GTF is supported, but the display does not support
continuous frequencies.
EDID conformity: FAIL"

I have no idea what that means and I only posted what looked relevant. I'm
going to retire that monitor and see if anything changes but I'm guessing
that's not the issue as I saw there were laptops having the same problem but
maybe it's an ASUS thing? Just a thought.

I use MPV. The only other video player that is installed (that I am aware of)
is VLC which I don't use.

I have 2 desktops, a laptop and a Raspberry Pi 4. I've only had the issue on my
main system but haven't checked the others yet. The rest are a couple months
behind in updates from lack of use and the laptop is old enough that it could
buy cigarettes where I live, if it were a person.

I'm going to try to setup a LAN over the next few days and attempt the
suggestion in Comment #37. I've never used ssh successfully, only have internet
via tethering or (with permission) my neighbors wifi and I have a disability
that effects memory (carbon, not silicon) significantly, so I would not rely on
me.

SOFTWARE/OS versions for main system:
Operating System: Manjaro Linux
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.9.0
Kernel Version: 6.12.21-4-MANJARO (64-bit)
Firefox 137.0
