Sorry to continue this old thread, but I’m not the savvy with this.
I’ve been using this pack for a while, but recently I updated the assets and shaders with retroarch and it messed it up. It now has this weird white glow around the letters and everything, I don’t know if I can fix this in the shader’s parameters or I have to do something about the updated assets.
Hi, “SirCharlesV”. 
You might be able to fix this problem by re-downloading a previous version of the emulator that was released around the same time as this shader, 6-11-2023.
Version 1.15 fits the bill: windows - buildbot.libretro.com > stable > 1.15.0 > windows (you can navigate to another version).
Alternatively, see if replacing the current shader folder with v1.15’s shader folder resolves the issue.
The folder is usually here, \RetroArch-Win64\shaders\shaders_slang
My suggestion is not to update the emulator unless there is a new feature or shader that you want to try out – cores are OK to update, though. I hope this is useful.
That fixed it. Thanks!

Yep, lesson learned!
Best thing is to revert to the version of Mega Bezel Reflection Shader you were using before you updated, or just stick with the version that @Zombeaver used when designing the Preset Pack. Next time backup before updating.
