bug#40224: 26.3; highlight-symbol-at-point does not cover entire buffer

Emacs - Bugs mailing list

 

 

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.

Yes, it refers to the number of characters.

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