/tmp folder full, ImageMagick tmp files

Hi, my /tmp dir is getting full very often. I found ImageMagick creates big temp files, after deleting them everything starts to work normally.

I have checked the package manager and everything is updated

I made a cron task to erase these files every 2 hours, but still happens anyways

Any clue how to sort this out?

This is my df -h command after deleting those files:
