This is still (very) experimental, and I’m not surprised that it doesn’t work yet. Try searching here https://github.com/linuxmint/wayland/issues and report a new issue if necessary.
As mentioned above by @r0ckhopper this is experimental so bugs like you are experincing are to be expected. Is there a reason you need to be using Wayland or are you just curios? Only asking out of my own curiousness
At this stage, it’s not ready yet. The Linux Mint developers are targeting Summer 2026 (after the release of Ubuntu 26.04 LTS) for it being fully ready. By all means open an issue at https://github.com/linuxmint/wayland/issues if there is not one open already, but don’t expect a quick fix.
