I am using Cinnamon on Fedora 39. I'm also tried Gnome, Gnome Classic, and Mate, but they don't allow as many of my accessibility needs. Cinnamon has accessibility settings to block blinking cursors and block other animation, but qt apps ignore these.

qt5noblink appears to be the only reliable way for users to block blinking cursors in qt apps: https://github.com/igogo/qt5noblink

I've tried other ways from here, but can't get them to work: https://jurta.org/en/prog/noblink

Running from the Terminal with LD_PRELOAD=[path to]/QtNoBlink/qt5noblink.so calibre --detach %U works, but

Opening the Menu Editor, and adding a launcher with LD_PRELOAD=[path to]/QtNoBlink/qt5noblink.so calibre --detach %U does not work. I get a "Cancel" button, and a grayed out quote "OK" unquote (sic) button.

I'm not sure if the Menu Editor requires different syntax, or if it requires more permissions, and what to do in either case.

I never used Cinnamon but it probably uses .desktop format for its menu items, and .desktop exec key expects executable as the first verb, not a random bash command. As usual, this limitation can be circumvented with a wrapper script but in this particular case using env may be simpler (env LD_PRELOAD=...)

Thank you, that worked!
