I ran into this, started up in safe mode (hold the shift key while launching). I disabled software fallback and was able to launch normally.

Asif, are you running with software fallback as well?

Comment 3

[Asif Youssuff]

Yes, I am running with Software WebRender.

Does the try build here fix the issue? https://treeherder.mozilla.org/jobs?repo=try&revision=260855f5c45d437d2b460f8b3864697cd64e64cc

Comment 5

[Asif Youssuff]

Matt, I am not seeing the issue in the try build.
