What I did was a hack.
I didn’t want to compile the binary, so I broke all references to the “bridge” responsible for blur.
This is not supported by anyone, and it could break your login screen. You should be prepared for anything to break.
My choice was to rename things while keeping the same string length, because binaries are position-sensitive. The compiler generates instructions that depend on exact offsets.
The string name was chosen only to make the change easier to undo, but it could be anything. I’m simply forcing this component to fail to load, hoping to avoid a segmentation fault and it worked. So, I was sharing hoping to make it visible and help those that are alright messing with things.
I hope this clarifies things. I should probably make a feature request…
TL;DR: It’s a hack. Do not try it unless you understand your system and have basic programming knowledge.
