Why is the legacyScreenSaver process using such a large amount of RAM, specifically 1.3 GB?

If you go into activity monitor click on the legacy screen saver and click the information icon, you should see a quit button on the bottom left corner of that box click on it and you can quit/ force quit the process.

I am having the same issue. I also use my own wallpaper (one from my camera roll) and the fliqlo screensaver. The screensaver just recently became a process for my computer which it used not to be. In the picture below it isn't using much storage but it's gone as high as 15gb and my computer only have 8gb or RAM. I have also noticed it has started to slow down my Macbook and am looking for a fix.

I got this, too; the main legacy screensaver may go up to 40GB, even 70GB today; what a crazy amount vs. a total of 16GB, so I think this is a bug.

Also, hundreds of legacy screensaver (web content ) processes consume 15MB per one.

Well i think this can be the first solution because before i'll do what i should do my RAM on my mac still stuck on 80% or gotta be more then what i've got is 74% RAM after force quit. Very helpful thanks a lot!

Since I upgraded to Sonoma, I have seen this process in the activity monitor, which uses around 1.3 GB of RAM.

How can I disable it?

Are you using a legacy screen saver...?

Try changing screen saver and compare your results.

it is the main reason that make fans speed go to more than 5000，when I quit this LLS process，the fan speed Would drop to about 2000.
