(Although I admit I'm beginning to wonder about myself.)
I've done a number of upgrades recently, and when I rebooted into kernel
6.3.3 yesterday, the boot seemed to go fine, but when I started
kde-plasma, things did not go well. I could vaguely see the "outlines"
of the desktop, but there was no recognizable wallpaper or any text.
The background was a solid light blue. I could see some which or light
gray boxes where there should be windows. If I move the mouse (no
visible cursor) to the top of the screen, something that might be the
panel shows up - but solid white. I see a tall striped window that is
probably gkrellm. Sometimes, I can right click on the desktop and guess
where the "logout" button is on the window that pops up, but sometimes I
need to kill things from a different console.
With no noticeable change in behavior, I've rebooted into the two
previous kernels (6.3.0 and 6.2.11) and rolled back plasma from ~5.27.5
to 5.27.4. I've reinstalled xorg-server 21.1.8, and all of its
xf86-input and -video drivers. I get the same behavior with an empty
~/.config or as a new test user. This is an amd64 system mostly stable,
with select testing apps. kde-apps are 22.12.3. I'm about to try
rolling back kde-frameworks from ~5.106.0 to 5.104.0 and mesa from
~23.1.0 to 23.0.3-r1. I haven't seen anything I recognize as a problem
in the X log, dmesg, or /var/log/messages.
I realize I'm not provide anything solid to go on. I do figure it's
something in my configuration or I would have found other reports. I'm
mainly hoping someone can suggest what else I can try or where to look
for hints, as I'm about out of ideas, beyond tracing back through all
recent upgrades.

(I figure there's a maybe 25% chance I'll discover the problem as soon
as I embarrass myself by posting this.)
