26.1; Gnome magnifier not following cursor when typing in emacs
Previous Next
Full log
Message #16 received at 35435 <at> debbugs.gnu.org (full text, mbox):
Hello,
For the record, it seems that cursor tracking does not work with the Mac
OS magnifier ("zoom") either when typing in Emacs. I tested this with a
Mac OS 10.15 virtual machine and installing Emacs from the following
sources:
* emacsformacosx.com
* Homebrew:
** brew cask install emacs: I was not able to complete the installation
for some reason but it is the same as emacsformacosx.com if I understand
correctly
** brew install emacs-plus
** brew install emacs-mac
* Mac Ports
** sudo port install emacs-app
** sudo port install emacs-app-devel
** sudo port install emacs-mac-app
On the other hand, cursor tracking worked correctly in e.g. the Safari
browser. So I guess the Mac port of Emacs does not have the "special
code to move the system caret in sync with the cursor" that the Windows
port has.
