Workaround: 1. Menu -> Preferences -> Applets (or Run `cinnamon-settings applets`) and open "Applets" dialog 2. Select "Download" tag in the "Applets" dialog and find "Menu" applet. 3. Click "Configure" gear button on the "Menu" applet and open "Menu" dialog 4. Select "Menu" tag in the "Menu" dialog and find "Keyboard shortcut to open and close the menu" configuration in "Behavior" seciton 5. Click the default "Super_L" button in the confnguration and change another shortcut key likes "Print". 6. Close all dialogs The you will find your customized setting is saved in $HOME/.config/cinnamon/spices/menu/0.json against /usr/share/cinnamon/applets/menu/settings-schema.json Now you can use Super-space from the first typing.
muffin in Cinnamon is similar with mutter in GNOME and once it binds XIGrabKeycode() fur Super key, it seems the key cannot be forwarded to IBus even if ClutterEvent filter gets FALSE. Seems XIGrabKeycode() is suppressed until the key is released. The usage of XIAllowEvents() with XISyncDevice and XIReplayDevice is complicated for me. Currently it's difficult to fix the isuse in Cinnamon side. Another workaround is to add a shortcut key in `cinnamon-settings keyboard` and I may consider a new command `ibus engine --switcher` in the future.

I can reproduce the issue in Fedora 41 but it would be a Cinnamon upstream issue.
Maybe someone can open upstream issue and/or this bug can be also reopened and targeted for F41.
