I know there didn’t used to be. I have visual processing issues and cannot see near any kind of flashing or blinking, and can get awful migraines and nausea from it.
I can’t see any text I’m typing in Draw, Writer, or Calc, or any objects I’m moving in LibreOffice Draw.
I mostly stopped using LibreOffice because of the blinding cursors, but I haven’t found any drawing software that lets me see the screen while working, and it’s important to be able to see the screen. I use related writing software which doesn’t have this bug.
There is no system-wide setting for cursor rates in MacOS. (P.S. The defaults write fix only works for some cursors in some applications.)
