Upstream requires wayland as required dependency so we can't remove the use depdency (bug #557428). *** This bug has been marked as a duplicate of bug 557428 ***
weird i build the package without and it was fine.
(In reply to C.J. Wijtmans from comment #2) > weird i build the package without and it was fine. Indeed in https://cgit.kde.org/kwin.git/commit/?h=d89777bcacb7b040076a783c7ef15558182407d0 Wayland::EGL is made optional again, but I'm not sure how we can sensibly expose that. A wayland USE flag doesn't make a lot of sense, because kwin still hard-requires other wayland components. I think we used to have an egl USE flag, but had to drop it because of bugs like bug #514920 and bug #563626. We could restore it, but it would need some testing to make sure nothing blew up again.
