Confirmed in 1.14.4
Here's another video. It occurs when destroying the block and when placing. It's really annoying cause the game just freezes for 0.2 seconds every time.

@violine1101 I tried turning of the entire nvidia overlay including shadowplay. And this did not fix it. I also have only one instance of minecraft running.
In 1.16.5 when using:
/setblock <x> <y> <z> minecraft:redstone_wall_torch[facing=south,lit=false]
It will place a turned off torch for like .1 second but then it will turn on again. So I can confirm the issue in this version as well.
