I can confirm that renderdragon needs to be removed or fixed. People are complaining about this. Bedrock has been very buggy lately since 1.16.200 released, I'm experiencing alot of lags and rendering problem, chunks takes so long to load. Renderdragon is the worst, my fps keeps dropping when i record, like bruh, minecraft bedrock takes up alot of gpu stuff than java, shaders aren't working in windows 10 too. The developers needs to remove renderdragon or they fix all these render issue and bugs.

I don't know alot about these kind of stuff because I'm not that intelligent  but this is my specs:

Intel core i3

Graphics Card: HD Graphics 630

Ram: 8gb
