Looks reproducible there, EGL+dmabuf.

Comment 8

[Martin Stránský [:stransky] (ni? me)]

Looks somehow tied to EGL window init (we don't see the crash on SW-WR) as there's the same pattern around

GetCompositorWidgetInitData()
GtkCompositorWidget::GtkCompositorWidget()
GtkCompositorWidget::GetEGLNativeWindow
nsWindow::SetCompositorWidgetDelegate().

Comment 12

[Martin Stránský [:stransky] (ni? me)]

Testing on try. In the worst case we can revert the initial EGL setup and return the EGLSurface delete/create cycle for X11.

Comment 13

[Martin Stránský [:stransky] (ni? me)]

Tested partial revert but without luck so far:
