Is there any way to turn it off in MacOS 15.7.3 or any other

This is a Qt setting. The following works on Linux Mint and may be
doable on MacOS.
1. Install the Qt 5 configuration tool (qt5ct on Linux).
2. Run the tool. If you get a warning about QT_QPA_PLATFORMTHEME
not being set, you have to add the line
QT_QPA_PLATFORMTHEME=qt5ct to an appropriate configuration file
and reboot. In my case, I was able to add it to
~/.config/qt5ct/qt5ct.conf. Other Linux users report putting it
in /etc/environment or other places. You'll have to do a little
research to find the appropriate file on a Mac.
3. Once the configuration tool is running without warnings, go to
the Interface tab and change "Cursor flash time" to 0ms. Click
Apply and then start LyX and confirm that the cursor is rock solid.
Note that this will affect all apps on your system using Qt5, not
just LyX.
I am not sure if we use Qt5 or Qt6 with the OSX packages, but qt6ct
also exists.
Looking at the source code, we do seem to get the cursor flash time
from Qt, so I'd expect us to respect this setting wherever it comes
from. If it's <=0, we do not start the blinking.
We had a ticket long time ago for this:
#9287 ((Accessibility) It is not possible to disable the blinking
cursor) – The LyX Project <https://www.lyx.org/trac/ticket/9287>
lyx.org <https://www.lyx.org/trac/ticket/9287>
trac.ico <https://www.lyx.org/trac/ticket/9287>
<https://www.lyx.org/trac/ticket/9287>
Right, and as you said elsewhere, there's a way to do this.
Looking at the code quickly, could the calls to
NSTextInsertionPointBlinkPeriod... be moved to
GuiWorkArea::startBlinkingCaret, and effectively take the place of the
calls there to QApplication::cursorFlashTime? That would make the OSX
version work pretty much like the other ones. In particular, if this
value were changed while LyX is running, we'd pick it up.
Also, this
#if defined(Q_OS_MAC)
int const cursor_time_on = NSTextInsertionPointBlinkPeriodOn();
int const cursor_time_off = NSTextInsertionPointBlinkPeriodOff();
if (cursor_time_on > 0 && cursor_time_off > 0) {
QApplication::setCursorFlashTime(cursor_time_on + cursor_time_off);
} else if (cursor_time_on <= 0 && cursor_time_off > 0) {
// Off is set and On is undefined of zero
QApplication::setCursorFlashTime(0);
} else if (cursor_time_off <= 0 && cursor_time_on > 0) {
// On is set and Off is undefined of zero
QApplication::setCursorFlashTime(0);
}
#endif
looks overly complicated. Why not just:
if (cursor_time_on > 0 && cursor_time_off > 0) {
QApplication::setCursorFlashTime(cursor_time_on + cursor_time_off);
} else
QApplication::setCursorFlashTime(0);
? The case where they are both zero seems not to be handled.
