Request #88414 has been Rejected by Auerhuhn [1]: The sonic-win PKGBUILD still `provide`s kwin-x11. The upstream maintainer is aware that kwin-x11 is gone on Arch (see matinlotfali/KDE-Rounded-Corners#543 [0]) but the upstream source still supports the `KWIN_X11` build flag even though upstream has removed it from its CI.
If you disagree, please co-ordinate with the current PKGBUILD maintainers, one of which seems to be the same person as the upstream developer. You can re-submit your request after you tried working it out with them first. [0]: https://github.com/matinlotfali/KDE-Rounded-Corners/pull/543 [1] https://aur.archlinux.org/account/Auerhuhn/
