Comment 1

[Bob Hood [:bhood]]

Based on the crash report, looks like a problem in the WebRender compositor. Dropping into Triage for the team to look at.

Comment 2

[Timothy Nikkel (:tnikkel)]

Two total crashes in the last 3 months. Same cpu, gpu, gpu driver version, os version. So looks like one machine and two crashes.

Comment 3

[Brad Werth [:bradwerth]]

Taking out of triage until and unless this increases in volume.

Comment 4

Closing because no crashes reported for 12 weeks.
