Duplicate of this bug: 1810297

It seems this needs to be backported to 109, see bug 1810297 comment 9.

Flags: needinfo?(stransky)

Looks like we missed time to backport it.

Flags: needinfo?(stransky)

Let's get this into the next 109 dot release. Please nominate when you get a chance, Martin.

  • Has the fix been verified in Nightly?: No
  • Needs manual test from QE?: No
  • If yes, steps to reproduce:
  • List of other uplifts needed: None
  • Risk to taking this patch: Low

Attachment #9308224 - Flags: approval-mozilla-release?

I wonder which build is that. Does Ubuntu 22.04.1 run Firefox on Wayland by default?

No, we're still running release builds under XWayland by default on Ubuntu. I was surprised to see Ubuntu crashes in there too, but I guess people can always manually force it to run with Wayland enabled still even if that isn't the shipping configuration. Hopefully that at least limits the severity of this in the wild (especially if Fedora's patching their v109 builds too).

Yes, Fedora ships downstream patch for it.
