You can add this screen to the force blur list manually. I'll include it in the next update.

Do you know by any change the exact name of this screens?? I just see the option you are refering to in the settings but idk the name to add it

For those experiencing this issue, turn off the fade from 300 to 0 in the config. it should fix everything.

Same problem right now.

OS MacOS 26.2
Minecraft 1.21.1
Fabric 0.18.4
REI 16.0.799+fabric
Blur+ 6.1.0+1.21.1-fabric (default config)

Looks like forceEnabledScreens simply doesn't work or the REI screen name is not valid.
The blur effect disappears when I go from inventory to REI recipe screen, BUT the "Gradient as Background" stays.

  "forceEnabledScreens": [
    "dev.emi.emi.screen.RecipeScreen"
  ],

What is interesting, forceDisabledScreens works when I remove/add ShaderPackScreen screen.

  "forceDisabledScreens": [
    "net.irisshaders.iris.gui.screen.ShaderPackScreen"
  ],

I prefer to play without gradient and only with blur.
I enabled the rainbow gradient for demonstration.
Please, keep in mind that forceEnabledScreens contains dev.emi.emi.screen.RecipeScreen during this demonstration.

inventory screen (blur + gradient):

rei recipe screen (only gradient):

@Motschen it looks like the new id for the REI recipe screen is:
me.shedaniel.rei.impl.client.gui.screen.DefaultDisplayViewingScreen

This id looks strange compared to the one you added by default. It's possible this id is only valid for my configuration. I tried adding the above id to the forceEnabledScreens array, and now the blur effect doesn't disappear (started working as intended, issue resolved).

This may not be the final solution, but it's a good starting point for further investigation.
