Massive Memory Usage? #1555

I downloaded Nightly to test out Webrender and the other new features, but after a while I noticed my tabs were freezing up, (especially) the Twitch video player. I then went to task manager and noticed that Nightly had pushed me to 90%+ memory usage with the main culprit being the Twitch tab from what I could tell. (along with high CPU usage)

Here's a screenshot of the Nightly memory usage

After disabling Webrender and restarting Nightly the problem has gone away and things are very performant again.

Info:

  • Windows 10, 64-bit
  • Nightly v57.0a1 (2017-08-06) (64-bit)
  • webrender & webredest enabled (also have Stylo enabled)

Let me know if there's any more information needed!

Possibly related to #1486 - we need to investigate what's going into the texture cache to use that amount of memory (I think ImageKeys may be getting re-created every frame for masks?).

@sotaroikeda ah, didn't see that. I did do a search on bugzilla but must have missed it.
