Issue was noticed after full rebuild for the upgrade to the 23.0 profiles, but may be unrelated to this.

Openrgb can start successfully after removing the effects plugin.

Comment 1 Andrew Ammerlaan gentoo-dev

This is caused by lto. Please add `filter-lto` from `toolchain-funcs.eclass` to the `openrgb-plugin-effects.ebuild`. Note that openrgb itself can be compiled with lto without causing this problem, it's just the plugin.

Other plugins may also be affected.

Nope, tested the other ones now and they are fine with LTO
