cursorline not highlighting "Operator" syntax group

[kakig]

The '=' isn't highlighted by cursorline.
I investigated and found this:

gruvbox/colors/gruvbox.vim

Line 590 in cb4e7a5

hi! link Operator Normal

call s:HL('Normal', s:fg1, s:bg0)
The syntax is setting the background back to bg0.
Don't know if it is intended behaviour but I find it very distracting sometimes.
Edit: typo.

I am also seeing this. Is there any workaround at the moment?

The same is true in case of floating windows:

Workaround: replace Normal with GruvboxFg1:

Sadly, resetting (hi! link Operator GruvboxFg1) in .vimrc doesn't fix all cases, need to fix the original line.

Any fix for this? I still have the issue in Neovim.

[lucalaissue]

Has anyone found a workaround for this ? Also having that issue

[chaudry-786]

in file ~/.vim/plugged/gruvbox/colors/gruvbox.vim change line 591 to hi! link Operator GruvboxFg1

can't we just remove the s:bg0 out of the call s:HL('Normal', s:fg1, s:bg0), that way the 'Normal' would be defined without a background and I assume this wouldn't be a problem anymore

[vhoyer]

or rather, I'm not even having this problem anymore, can anyone confirm that this is still a problem, and if it is provide a minimal reproduction to this issue? if you need a model, you probably can use this one I made as an example: https://github.com/vhoyer-bug-reproductions/airline-freeze-on-C-c

@vhoyer Here is the minimal example: https://github.com/kakig/gruvbox-cursorline-hightlight-bug

In the second line of the vimrc you can still see the bug happening:

[vhoyer]

well, as pointed out the the OP, the problem is in the Normal highlighting group and so it happens whenever this group is linked to another things, for example in a vim file, the highlighting for the vimUserFunc group which also is linked to Normal has the same problem.

so what has worked for me as a workaround is defining after the colorscheme gruvbox:

highlight Normal guibg=NONE ctermbg=NONE

[vhoyer]

Turns out setting this hihglight rule I pointed as a workaround, messes with the airline coloring, so, use at your own risk ahah

[vhoyer]

if the problem is exclusively with the operator you can always just

hightlight Operator ctermbg=NONE guibg=NONE

haven't test this tho
