10.12.4 Increases Cursor Blink Rate

It was bad enough before. It's several flashes per second now. It's hard to see around, it will trigger migraines, and at such a high frequency, it might trigger seizures.

I switched from Safari and Mail to Firefox and Thunderbird because I can use the about:config fix to stop the strobing/flashing/blinking cursors, and switched frm LibreOffice to NeoOffice because I could use the terminal hack to switch the rate in NSText apps. But I still can't block it in most Webkit apps and can't avoid all Webkit apps.

Is there any way to slow down the cursor pain rate?

MacBook Air (11-inch Mid 2013), macOS Sierra (10.12.3)

After reloading, NSText is operating alright, and NeoOffice 1/20 seconds, while Webkit is operating at about 2 flashes/second, when I've used Tinkertool to set it to 1/second, the slowest available setting.

Correction:

Older NSText is operating alright.

Newer NSText is refusing to accept user settings, strobing, and triggering user migraines. It has returned NSTextInsertionPointBlinkPeriodOff and On to 500 each, and refuses to allow long, reasonable, non-migraine inducing periods such as 10000.

I get an error stating "Unexpected argument 10000; leaving defaults unchanged." As the Mac refuses to stop punching me if I dare to use Textedit.

Okay, using "defaults write -g NSTextInsertionPointBlinkPeriodOff -float 10000" and the same with "...On -float 10000" solves that.
