[gentoo-user] kde-plasma seems to have lost its mind

[gentoo-user] kde-plasma seems to have lost its mind

[Jack]

(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.)

Pretty much as I figured - downgrading mesa from 23.1.0 to 23.0.3-r1  
has plasma working just fine.  I'll test again with 23.1.0 and file a  
bug if the problem is repeatable.
