Try running plasma 6.0.2 from opensuse tw unstable repos, result in:

`kwin_wayland: symbol lookup error: /lib64/libkwin.so.6: undefined symbol:
drmSyncobjEventfd`

software versions: 
libkwin6-6.0.80git.20240419T230656~fba948b3-ku.41.1.x86_64
libdrm2-2.4.120-1.3.x86_64

libdrm2 already satisfies what is required here:
https://invent.kde.org/plasma/kwin/-/merge_requests/5610

running 'nm -D /usr/lib64/libdrm.so.2 | grep SyncobjEvent' returns 
000000000000c0b0 T drmSyncobjEventfd

tried also rpmrebuild, no success.
