Problem with the game after some recent updates. Graphic bacchanalia

After 10-20 minutes of play, or a couple of completed maps after a small lag, a total flex of all pixels and models on the screen begins: all rare mobs are stretched in parts to fill the entire screen, magic mobs are scattered into hundreds of small stripes like an LS attack, regular mobs are practically unchanged, the floor texture becomes semi-transparent, and the most interesting thing is that the mini-map opens completely (i.e. the fog of war goes away and all the outlines of the map are visible right up to the boss, despite the fact that I did not run there). You can continue playing - but you can't see anything at all that is happening on the screen, just a mess of stretched mob models. Has anyone had similar problems and does anyone know how to fix this? There is nothing like this in other games.
