Subject: 26.3; highlight-symbol-at-point does not cover entire buffer
Date: Wed, 25 Mar 2020 15:24:27 +0000

[Message part 1 (text/plain, inline)]

In a buffer with about 2000 lines, highlighting words at the top of the
buffer with highlight-symbol-at-point does not have any effect way down
the buffer. It stops highlighting at about 1500 lines. The bug
happens with emacs -Q as well.

Can you show a detailed recipe, including the file you use for this?
I tried reproducing, but I don't think I succeeded.  So there must be
something that I did wrong.

Thanks.

Please try to increase the number in M-x customize-variable RET
hi-lock-highlight-range

That did the trick. It was already quite high (20k) so I guess it refers to the number of characters and not lines.

Yes, it refers to the number of characters.

I propose to bump the default value from 200KB to 2MB:
