Very much lag with the new renderdragon, and the background is changing color.

Hello. In the last beta that came out yesterday (1.17.40.20) I noticed that they added the new "renderdragon" system, but in gameplay I'm with 6/7 fps, and that bothers a lot. Yes, I've already reduced the chunks as much as possible and continues lagging excessively, the graphics settings are at a minimum and it doesn't solve it. Usually my gameplay before this version was 50/60 fps, however that number dropped to 6/7 fps and that's bad.I just want you to improve the game's performance with the new renderdragon graphics.

O Regarding the inventory bug, when I open the inventory in any item tab, the background changes color for a few milliseconds and then goes back to normal.I've seen the color yellow, pink, green and cyan, and I believe it's a bug. Thanks for reading this.
