• Description: Open any GTK4 app, and move the mouse cursor into the window. The window can be interacted with normally by using keyboard controls.

Can you provide a WAYLAND_DEBUG=1 log of your client?

WAYLAND_DEBUG=1 your-client >client.log 2>&1
# Then reproduce the bug

[tokyovigilante]

Thanks for reviewing, WAYLAND_DEBUG log attached. client.log

[emersion]

Weird, the stack trace indicates a crash triggered by wl_abort() but the error message is nowhere to be seen.

[danielcb]

Same issue, same error message. Also on fedora rawhide.

[tokyovigilante]

I saw #8115 and #8232 and thought that PR may have helped, but can still reproduce this with current HEAD (818ea173) which includes this fix.

[tokyovigilante]

Have just updated Fedora (including libadwaita) and GTK4 applications are no longer crashing, so presumably this was a GTK bug which has been fixed, although I didn't see anything in Bugzilla about it. @danielcb if you could also update and confirm resolution I will close this.

[danielcb]

Yep, I can confirm that after the recent updates the bug disappeared.
