I'm running into a really annoying issue with my Ubuntu installation. Even though my home drive shows that there's plenty of disk space available, I keep getting notifications saying that it's full. This has stuck around no matter what I try. I've also noticed that Chrome isn't keeping me logged in properly between sessions and keeps throwing notifications about cache issues, leading me to clear my cache frequently. Given that this is a fresh install of Ubuntu—only about a month old—it's perplexing. Additionally, when I'm playing Steam games, the loading time for Vulkan shaders is really slow, and if I try to let it load in the background, the games become super stuttery.
Recently, I tried installing Fusion 360 through Bottles using the default settings, but that failed numerous times. After several attempts, my drive started filling up, and I even booted into recovery mode to clean things out. I cleared a lot of unnecessary files, so I'm sure there shouldn't be any leftover junk. When I run the `df -h` command, it shows everything is under 10% used, except for the root (/) partition which is now at 78% after some light use since checking. I also looked into inodes, and there's plenty of space there. I've tried running `sudo apt-get clean` and related commands too. After restarting, the root partition shot up to 93% used! I'm using a 120GB SSD for my OS, and the space used has jumped from about 50GB to 96GB in a few short hours. Any ideas on what might be causing this?

It sounds like your `tmp` directory might be filling up and causing these issues. Check that directory and see how much space is being used. Sometimes log files can also get way out of hand. It's worth a look!
Looks like you're checking the root partition's usage. Can you clarify what the notification says? Also, is your `/home` directory a separate partition, or is it merged with the root?

The notification says 0MB 0% full currently.
