(Keywords: stalled)

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0
Build ID: 20190801214227
Shockwave Flash 32.0.0.223

Preconditions:
Install a 32-bit build on a Windows 10 x64 machine

Steps to reproduce:
Launch Firefox, log-in to Facebook and run each of these games in new tabs:
https://apps.facebook.com/angrybirds/?fb_source=appcenter&fbs=126&fb_appcenter=1
https://apps.facebook.com/coral-isle/?fb_source=appcenter&fbs=126&fb_appcenter=1
https://apps.facebook.com/ghosttales/?fb_source=appcenter&fbs=126&fb_appcenter=1

Expected results:
All games are loaded and can be properly played.

Actual results:
The 3rd game won't load anymore, and playing the other 2 games becomes difficult.
When webrender is disabled, the games run a bit better.

Firefox becomes really unresponsive sometimes and crashes, here are some examples of the crash reports:

Nical - were you ever able to get a 32-bit build going to see if we could reproduce this?

Let's consider this one stalled for now. I have a fair amount of less contrived bugs to look into and I haven't figured out how to even get that 32bit build on windows 64 thing going.
