There is a graphics problem and mirror flickers whenever I play the game. Anyone who encounters the glitch can help? It's totally annoying.

This glitch happened on a save file after I finished the graphics settings. No matter what, if Advanced Rendering is off 또는 on, that glitch 암캐, 암 캐 still happens! It continued on other save files no matter what town. It is the WORST FUCKING GLITCH ever! Anybody who knows about how to fix the glitch should immediately answer this question. I need help on the glitch.
