I'm facing a really annoying issue with my Ubuntu setup where I keep getting notifications about my home drive being full, but when I check, it shows that there's plenty of space available. I've also noticed that Chrome isn't remembering my login sessions and I've been frequently prompted about my cache being full, so I've been clearing the biggest files. This shouldn't be happening since my Ubuntu installation is fairly new, only about a month old.
Additionally, whenever I play Steam games, the loading of Vulkan shaders takes a long time, and if I try to load them in the background, the games become really stuttery. Recently, I tried installing Fusion 360 through Bottles, using their default installation options, but after several failed attempts, my disk started to fill up. Eventually, after a restart, I received a message about the TMP drive being full, which prevented me from booting properly.
I managed to fix this by booting from a USB, deleting unnecessary files, and using recovery mode to clean things up, allowing me to boot successfully again. Despite this, I've continued to face issues. Running the command `df -h` shows everything below 10% usage except for the root partition, which has been fluctuating from 59% to now 93% even with minimal usage.
Checking inode usage reveals I still have tons of space there. I've also run commands like `sudo apt-get clean` and its related commands. It's becoming increasingly puzzling, especially since my OS occupies a separate 120 GB SSD, and I've had to use that for various installations due to other problems. The sudden increases in space used just don't add up over the past few restarts and recent updates.

You're likely looking at the root partition's usage. Can you check the notification details? What's the percentage on your `/home` directory, or is it part of the root? It might be worth checking where exactly the space is being reported as full.
It sounds like the `tmp` directory might be contributing to your disk issues. You should definitely check that, and also see if there's a problem with log files filling up the space.Those can add up quickly if they’re logging too much information!
The notification says 0 MB used and 0% full, which is super confusing!
