[Solved] Unusable KDE desktop after recent update and reboot
I've just recently installed some updates and reboot, but found my KDE desktop in an unusable state. X and sddm both start fine, but when I log in I get three windows saying Plasma closed unexpectedly and another saying desktop effects are disabled. My main panel does not show up and there are graphical glitches when moving the windows around.
Here is what seems to be relevant from journalctl:

Re: [Solved] Unusable KDE desktop after recent update and reboot
Do you have this problem with kernel 4.4 (or could you downgrade to 4.3 to see, if that problem still appears)? Only asking, because I have a problem with Plasma with kernel 4.4.

Re: [Solved] Unusable KDE desktop after recent update and reboot
I encountered this problem with kernel 4.4.1-2-ARCH, but since that is the kernel I was previously using without issue, I'm inclined to think that is not the cause, unless some other recent update has compatibility issues.
Downgrading did seem like a good idea, though, so I decided to follow the instructions in the wiki to downgrade to 02/07/2016 (the last time I did a full update). That proved difficult, though, since some nvidia files were recently moved to libglvnd package. Pacman wouldn't let me overwrite them with the old nvidia package and I couldn't uninstall libglvnd without practically uninstalling my entire system. I ended up moving the affected files to a backup location so pacman would proceed with the downgrade.
After the downgrade completed, the desktop environment appears to be working properly. So that's good. But I'm pretty sure my system now is in some kind of weird, invalid state with respect to packages. How do I fix that?

Re: [Solved] Unusable KDE desktop after recent update and reboot
Although I initially thought I might have messed things up by messing around with 32-bit libraries, I no longer think that is the case.
Downgrading successfully got things working again. After that I tried updating everything back to current. At that point I had trouble getting sddm to start, but re-installing all nvidia packages and libglvnd fixed that. But then I had the same segfault / core dump problem that I initially posted. So I had to downgrade again.
I'm starting to think this is probably a bug... maybe in the nvidia drivers?

Re: [Solved] Unusable KDE desktop after recent update and reboot
Have you installed the microcode update for your processor? I'm not sure if it will make a difference, but a lot of random crashes can happen if the microcode is not updated.

Re: [Solved] Unusable KDE desktop after recent update and reboot
Thanks for the suggestion! I was under the impression that microcode updates were handled by the kernel and was unaware that an additional package needed to be installed and configured for Intel processors.
Unfortunately, after installing, configuring, and verifying the microcode updates, I am still getting the same result with the most recent packages.

Re: [Solved] Unusable KDE desktop after recent update and reboot
Okay, I think I managed to track down the cause of this after some further forum sleuthing.
I came across this thread talking about recent nvidia driver updates causing games to complain about OpenGL version (sounded familiar). That thread links to a thread on nvidia devtalk that mentions the driver causing issues with __GL_THREADED_OPTIMIZATIONS (also sounded familiar). Some time back, I had added `export __GL_THREADED_OPTIMIZATIONS=1` to /etc/profile as part of an attempt to rid myself of incessant video tearing.
So I changed /etc/profile to export `__GL_THREADED_OPTIMIZATIONS=0`, update packages, re-installed nvidia/libglvnd packages, rebooted and... all seems to be working well. Except the incessant video tearing that I had solved at some point, but then came back with a vengeance a few months ago and I haven't been able to be rid of it since. But that's a topic for another day.
Thanks to all who offered suggestions!
