How can I fix my distorted options icons?

@Riyan4510209  The only way to fix this is to remove the offending mod.  Start with UI Cheats.  If that doesn't work, you can use the 50/50 method to sort through your mods:

You can of course keep all the mods and custom content items that still work properly.  If you load a new save, your existing one(s) won't be affected by the temporary absence of your mods and cc.
