Very few crashes (in Thunderbird). It's new because webrender wasn't used before. I forget if it's even on by default in 91.

This one is quite rare. But there are others

• webrender in top of stack
• webrender in stack
• The predomment crash is Bug 1721278 - Crash in [@ wr_moz2d_render_cb]

For Thunderbird, this is gone after 102.4.2.
