AtlasCache folder keeps getting huge

Does anyone know why the AtlasCache folder in the Library directory keeps getting huge? I can close Unity and then delete the folder and it returns to a regular size but if I leave it alone for a few days, it balloons up in size. Normally it wouldn’t be a big deal but I’m transferring the files back and forth between machine frequently and it’s just one extra annoying step I have to do every time.

I’m experiencing the same issue. I’m not positive its a bug per se, but it becomes cumbersome when running backups.

For now, I’m going to add a command to delete this directory during each backup. If you’ve found a resolution, I’d like to see it!
