Permissions and 3D renderization errors after full-upgrade

Support
1

I’m trying to make a full upgrade of my laptop, but after update I have some error of cpu dump and some apps exit with error, for example neovim with lazyvim and signal application. I get an error in signal that I didn’t have before the update at the same than neovim, it exists with a “core dump” error.

My cpu is last generation and the laptop doesn’t have GPU, so it’s not from drivers or incompatibility between cpu and some new feature.

I’ve tried removing grub boot params and adding user to video and render groups. It looks that it¡s an error of permissions or compatibility with some package I already had installed. These are the package installed in the full-upgrade.
Any idea which could be the cause? I will try to debug it anyway but I don’t see errors in journal related with this.

Do you know what exactly updated that triggered this?

Some months ago, when I used to regularly use KVM on a Kubuntu 24.04 system, I noticed that every so often my browser (Google Chrome, I know it’s a privacy nightmare, but for my non-anonymous browsing I live with that intentionally) would crash, all Electron-based apps would crash or behave erratically, and one or more KVM VMs would crash, all at the same time. How or why, I do not know. Signal is an Electron app (which uses Chromium under the hood), so maybe you’re running into something similar.

“Do you know what exactly updated that triggered this?”

No idea at the moment. I will have to test each package and debug it to try to find which one is causing the disruption.
But btw I have this issue in baremetal too and I’m trying to replicate it on VMs. I’ve set up a clean debían machine and I’m installing kicksecure individually to try to find what configuration/package could be causing it.

In my machine libvirt crash with 3D acceleration enabled and exit without any alert sometimes, and I have to reopen it, although the machines continue running in background. All this is after the upgrade, but I reverted all with timeshift.

I will try with .appimages too, if it works, maybe the issue is like configuration or permission. But I have no idea
