Check the filesystem -- it's in RAM by default using tmpfs, and tmpfs
defaults to a size of half of physical ram. To disable and go back to haivng it be part of /,

  sudo systemctl mask tmp.mount

To change the limit while leaving it in-ram, I assume you'd put the desired
size in the Options line in the systemd tmp.mount file, but there may be a
better way.

I believe the argument is that if Brasero needs more space, /var/tmp would
be a better place.
