High memory usage in Atom 1.18 beta

[simurai]

Originally reported here: atom/atom#14436

In Atom 1.18 (currently beta), having a few files open and then enabling this package seems to use a lot of RAM (some GBs).

Console shows:

Might be related to adding snapshots atom/atom#13916, but not sure.

Same here. 😢

macOS 10.12.5
Atom 1.18.0-beta0

[Ben3eeE]

I have the same problem on Windows 7.

[MD-ThorErik]

It leaves my system out of memory with a certain project folder too.
Atom : 1.18.0-beta0
Electron: 1.3.15

Also confirmed on my system. Fresh Atom install with only pigments running. Node and Electron are both up-to-date with the Arch/AUR repos.

[sbstnmsch-zz]

Same here on 0.39.1 and Atom 1.18.0-beta0. When Pigments is enabled it will boost an Atom Helper Process to CPU loads constantly higher than 100% and high RAM usage after opening a single file, no matter what type. I'm on a Macbook / MacOS 10.12.3.

[nibushibu]

In the latest beta version, the problem seems to have stopped occurring.

macOS 10.12.5
Atom 1.18.0-beta2

[Cxarli]

Not sure what caused it, but I'm glad it's solved.

[ekfuhrmann]

I'm on the latest beta build [1.18.0-beta2] and still experiencing the massive memory issues on Win10.

[phyllisstein]

This is ongoing for me as well, in Atom 1.18.0-beta2.

[ekfuhrmann]

Is there any update on the progress of this? 1.18 is now the stable release of Atom and this still is not resolved, rendering Pigments entirely unusable.

[xzilja]

+1

[NoahDavidATL]

I like the concept of Pigments, but in its' current state it makes ATOM unstable (and in my case, causes it to freeze outright).

Closing in favour of the master post.
