cursor appears in the wrong position when using blue or darkblue default colorschemes

Problem

Cursor appears at the wrong position when moving into an opening bracket, parenthesis or braces. Notice how the coordinates are correct but the cursor position shows up as if it were the matching parenthesis highlight.

Steps to reproduce

:colorscheme blue or darkblue
write foo(123)
move the cursor using hjkl

Expected behavior

cursor should move normally over the parenthesis and matching parenthesis highlight should be appearing correctly

Nvim version (nvim -v)

Vim (not Nvim) behaves the same?

yes, vim 9.1.1734

Operating system/version

Arch Linux

Terminal name/version

Konsole 25.08.1

$TERM environment variable

Installation

pacman

Can't reproduce. Please make sure to test with nvim --clean and report the output of :set tgc?.

I used nvim --clean in the video and the output of :set tgc? is termguicolors. It also happened on another machine with linux mint on a clean install of neovim

Can you try the latest nightly?

Cursor is likely in the right position, just illegible; you're confusing the other MatchParen cell as the cursor instead.

Colour schemes like blue define MatchParen as reverse, which when combined with a terminal that also reverses the cursor fg/bg ends up "cancelling out" its highlight.

These same schemes usually define Cursor to be legible here; does :set tgc gcr^=a:Cursor happen to help in your case?
