Update: Switched from gnome-console to gnome-terminal, yet this still persists. Tried on Blackbox too, same issue.

Sorry for the late reply, I didn't get a notification...

Unfortunately I can't reproduce your issue, could you maybe share your config so that I can try reproducing it?

Also it is unlikely that this colorscheme is responsible for those artifacts, this colorscheme is only providing the colors, the issue is much more likely to come from your statusline plugin.

colorscheme PaperColor

When my vim was at minimal configuration, I was using this repository, but most of the schemes were broken and a few of them had the same issue as the one I am facing with vim-prism. NLKNguyen/papercolor-theme seems to work properly with vim-lumen on my device.

By any chance, could it be that the themes don't work properly on Vim, but only Neovim?

[vimpostor]

Well I tried your config both in wezterm and gnome-terminal and can't reproduce any artifacts. Maybe try out a different non-Gnome based terminal emulator or try out a different font, in any case this color scheme is probably not at fault for those artifacts.

By any chance, could it be that the themes don't work properly on Vim, but only Neovim?

No, this colorscheme works just as well in vim as it does in neovim.

[Ashvith10]

I guess the problem is probably with the powerline-fonts provided by Fedora. I was able to use symbols without a patched font, but now that I've installed a patched font and removed this package, everything works fine.
