Cosmic desktop uses a separate executable just for alt-tab. Currently there is a bug where sometimes it falls to grab ahold of a surface when the system wakes from sleep, and the process dies, and then alt-tab doesn't work.

If I run my distro's updater, and I then reboot when it asks me to reboot, I expect my system to properly start up.
I've had that not happen so many times now that before rebooting I ask Claude if rebooting is safe.
Most recently I was informed that my kernel had been updated, my old graphics driver uninstalled, but the installation of the new graphics driver had not proceeded as expected. Mind you the updater reported everything as a-ok.

But not an experience for non-technical friends.
I am using Nvidia so I have to be very careful. I regularly run into issues with system vs flatpak driver versions getting out of sync and losing acceleration in most of my apps. Thankfully it has happened so many times now I know how to resolve it quickly.
It may have been ok anyway. Without further details we can't say. Most drivers are included with mainline kernels so your "old graphic driver" may have been an out of distribution gfx driver (nvidia?) that doesn't support new version of kernel for example or said driver may have been replaced by something else with a different name.
