> I noticed a change in the default cursor colour of emacs 29. It seems that in emacs 28.2 (at least) the cursor colour is inverted when it is on a background of the same colour but in emacs 29 the cursor colour is not changed making it impossible to see.

> For example, the following code inserts text with a black background (same as the cursor colour). When the cursor is on top of this text in emacs 28.2 it becomes yellow'ish but it is invisible in emacs 29.

I cannot reproduce this problem here: I get a "yellowish" cursor in
Emacs 29 as well.  And I'm not aware of any changes in this area
between Emacs 28 and Emacs 29.

On which platform is that and with what Emacs configuration?  (Using
"M-x report-emacs-bug" would have collected this information
automatically for you.)

Thanks.
