Unfortunately, this is still an issue even after 15.3's release. The only way I know of to fix it, is to downgrade nemo's packages to the ones found here: https://build.opensuse.org/project/show/X11:Cinnamon:Current I should note I do not use a display manager, I just launch my X session through startx/xinit. I've also tried deleting all of nemo's config files, and that doesn't work either.
