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

The cursor in Emacs 28.1 on Windows is broken. I want a blinking
cursor. To get a blinking cursor, I have to disable cursor blinking. In
other words, the function is set up backwards. I cannot get a box
cursor. Only a line cursor is available to me. Sometimes I see cursor
artifacts on the screen.

These problems do not exist in Cygwin's 28.1. There, the cursor in Emacs
works as it
should. I have tested GNU's own 28.1 .exe and another one compiled by a
Reddit
user who made native compiles with AOT, and both have the same cursor
problems on Windows.

I cannot reproduce this.  The cursor blinks for me on MS-Windows as
expected.

Some questions:

  . does the problem happen if you invoke "emacs -Q"?
  . are you invoking the GUI version of Emacs or the text-terminal
    version (by using the -nw command-line switch)?
  . what kind of "line cursor" do you see? is it a vertical line or a
    horizontal line? what is the value of the cursor-type variable?
  . do you have w32-use-visible-system-caret customized to a non-nil
    value?

By default, Emacs's cursor only blinks 10 times and then stops; it
resumes blinking after some input event.  Are you sure what you see is
not this behavior?

Thanks.

No need to be sorry.  I'm glad you have your problems fixed.

I'm therefore closing this bug.
