Running Minecraft Bedrock at close to 21:9 Aspect Ratio with RTX gives me major artificing and screen corruption with only half the screen rendering.

I have screenshots uploaded highlighting the issue. In Windowed mode I was able to get Minecraft running at about 2:3rds of the width of the screen. But you can see that when I widen the window from that point, the visuals break; only half the screen is rendered, with broken clouds, vertical slices, smearing and other artifacting. This happened in all RTX texture packs I could test.

As wide as I could manage before the issue occurred^

A Fraction Wider Screen^ - Obvious rendering issues and smearing - Unplayable

Full Screen^ - Obvious rendering issues and smearing - Unplayable

Full Screen^ - Without RTX
