Running `git blame` pointed me towards this thread. While the bug has been fixed on master and it's rather tricky to reproduce (it involves at least one third party package for me and typing a long line at the end of the window that then wraps around), I'd be inclined to call 27.2 more than just a bugfix release due to the xdisp.c change introducing this bug. Is there a chance that a patch can be published for the 27.2 release for downstream maintainers? --riHcMJMdb75I/n90 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE0dAcySl3bqM8O17WFmfJg6zCifoFAmCL4/oACgkQFmfJg6zC ifor5ggAnJbGn94+c1XE5WNa7r87BreN+Xm4MxNeWLnUCXRIQ4ho1k90gal4gNUM gHSa+5NagaCdNV273ffjJozxA3asnoGPvVa3gZTlk22hbESQ/x9EDFal8lnsRfqX WdCB1RFKNgfARBza+nuy5gUBy0ug+zynBRc87GvSbgwhSIzY3p7uCqMEjl97Bekp VsEhDVcnafTFqAMUZp+2Xp8X5wjW/iGaWmGzEPBjD5YnoheuK9U9/8m/8p0h2U6x F52Ms+NNvM5xiz3ZFJnCZp+5Ny9YyMlLxJhSpxB4Sm6+SKwDf3Ot3Es3z0yf3tDb TpkyiCtupAs54x8o/lsr4Ipf+2JohQ== =P/AZ -----END PGP SIGNATURE----- --riHcMJMdb75I/n90--
