1744317 - Crash in [@ X11Error] | X_GetImage: BadMatch (invalid parameter attributes)

Status: RESOLVED DUPLICATE of bug 1741956

(Core :: Widget: Gtk, defect)

Description

[Chris Peterson [:cpeterson]]

This is not a new crash signature, but it increased a lot in Firefox 94:

• 15 crash pings from Firefox 92.0.*
• 20 crash pings from Firefox 93.0.*
• 17,065 crash pings from Firefox 94.0.*

Could this be related to the Fission rollout or WebRender changes in 94?

This seems to be bug 1741956:
(Lee Salzman [:lsalzman] from bug 1741956 comment 5)

The X error that is ultimately causing Firefox to crash is a BadMatch error that is spouted by a GDK error handler.
