For one additional detail, the popover thing in this case is wayprompt.

Comment 2

[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you try to use mozregression to find the broken commit?

Thanks.

No, I can't really since I'm on NixOS. This is easy to repro and trivial repros with anything making an xdg pop up. It's certainly still happening, still getting one or more crashes a day from it.

Okay, Please try to use different compositor (in tested mode):

Thanks.

Sunk a half hour into this, can't even build wayprompt on ubuntu because wayland-protocols are out of date. I'll look for another client that uses the same mechanism to draw on the screen.
