Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P3)

Description

Flipping WR on the other day, may system stared pausing running process as Firefox main process was suddenly on 50GB RAM. I checked twice again, process pausing after ~60 minutes, second test 3GB after a few minutes.
This doesn't happen for me on another machine with macOS 10.11 running.

Note: When it happens, Lastpass requires authentication again.

A big image leak was just fixed in the last day or so. Can you see if you can reproduce it with today's Nightly?

Hey Jeff, 
It is still happening for me (on 7.5GB while replying). I am testing 61.0a1 (2018-04-26) | build ID 20180426220144, should it be fixed in this version?

Yeah, the problem I was referring to should be fixed in that version. Is there anything specific you need to do to reproduce the problem? Can you attach an about:memory report to the bug?

Comment 4

[Albert Scheiner [:alberts]]

Will try to do that on Monday

Jeff, I saved this when the main process used ~7Gig. Let me know if you need another one. BTW, that was with latest build of today 61.0a1 (2018-04-29).

A number of memory leaks have been fixed since this bug was filed. Are you still able to reproduce?

[Albert Scheiner [:alberts]]

Having WR enabled by default for a while already and no such issue anymore.
Just FYI, I am on macOS 10.14 already. Still closing this ticket for now.
