I use a custom PS1 prompt in .bashrc as,
export PS1='\e[1;33;40m\h\e[1;31;40m root\e[1;37;40m@\w\e[1;37;40m\e[m\n## '

If I take out the \n from my PS1, ctrl-r in bash is problematic.
Scenario i use to test,
vi .bashrc, edit PS1, (ctl-z), then I type bash, then ctl-c to see if there's
an issue.
When trying ctl-c, i would type a few letters to match a history command, then
tap the left/right arrow.
What I get is display corruption on the prompt line after tapping left/right
arrow ..
PS1 with \n -> no corruption
PS1 without \n -> corruption

The issue here is that the escape sequences are not surrounded by \[ and
\]. From
<https://lists.gnu.org/archive/html/bug-bash/2023-09/msg00093.html>:
The man page states
PROMPTING
[...]
\[ begin a sequence of non-printing characters, which could
be used to embed a terminal control sequence into the
prompt
\] end a sequence of non-printing characters
