Sims 4 Notification Wall Graphic Glitch

@Jacey24 Please re-try running a game repair in the following manner. If you do not have mods or cc then just do the rest of the steps. If you used to ever have mods or cc that you removed, still follow all steps so that the mods folder gets entirely re-created:

Please try the following:

• If you have mods or CC, please copy the Mods folder from your 'The Sims 4' folder to your desktop (for future reference) then delete the mods folder and the localthumbnailcache.package file in your 'The Sims 4' folder and restart the game and so that the game will re-create the folder.
• Then run a game repair [ Open Origin, click 'Game Library' then right-click Sims 4 > Repair Game ]. After that, please see if the issue has stopped. 
  (If It fixes the situation you can re-add your mods/cc one at a time to see if one was conflicting with the function/causing the glitch - but do not re-add the old config file from the old mods folder, as it is possible for it to have become corrupted also.)

Let us know how it goes.
