Tested with mutter version 50.1-0ubuntu2.1 from -proposed on Ubuntu Resolute.
Testing performed: installed the package from -proposed repository and verified that the bug described in this report no longer reproduces. System behavior is correct and stable after the update. Testing performed following the test plan: - Installed Steam / Slack via Snap. - Launched the application and clicked on menu bar items (e.g. "Help") → popup menu appears correctly. - Verified right-click copy/paste functionality works as expected. P.S. Thanks a lot, today my two remaining Ubuntu 26.04 issues finally got fixed! :D ** Description changed: + [Solution] + + Tested with mutter version 50.1-0ubuntu2.1 from -proposed on Ubuntu + Resolute. + + Testing performed: installed the package from -proposed repository and + verified that the bug described in this report no longer reproduces. + System behavior is correct and stable after the update. + + Testing performed following the test plan: + - Installed Steam / Slack via Snap. + - Launched the application and clicked on menu bar items (e.g. "Help") → popup menu appears correctly. + - Verified right-click copy/paste functionality works as expected. + [ Impact ] After upgrading to Ubuntu 26.04 (current development branch), some Snaps have lost core UI functionality.

The issue is consistently reproducible with the Slack and Steam snaps. This seems to only affect snaps that use X11 through Xwayland, but it could, in theory, have larger unknown side-effects.
