Summary
Olive dumps cache files into the current working directory you are in on Linux, originally saw the behavior when it filled my home folder on Gentoo Linux.

For the sake of having a reproducible environment i tested this on Ubuntu 20.10 vm and latest appimage (as of c03c197) where it occurred also.

With the help git-bisect found the original source of the behavior to probably be 6c30f8c.

After testing 7b4e709 I see that behavior has changed in that the cache file isn't created when putting a video on the timeline, but cache files are still created in the current working directory when exporting.
