Incorrect frustum culling on ultra-wide display

I have what I believe to be a frustum culling issue when playing Minecraft Java on an ultra-widescreen (32:9) monitor. The issue is that chunks seem to disappear once they are being displayed outside the usual 16:9 screen area.

Tested seed: -2323201294763458300
Near coords -1033 20 -902

Issue goes away when turning slightly to the right:

For me some of the chunks are even not visible with a normal screen resolution with the given seed and coordinates in 21w05b. This might be caused by MC-70850, but I am not completely sure so I will leave this report open for now.

Can this still be reproduced in 21w11a or later?

@@unknown could you please check if you are still experiencing this issue in 21w11a or a newer version? The fix for MC-70850 might have solved this.
However, due to world generation changes the provided seed and coordinates do not have the same terrain anymore.
