Apple Vision Pro - Ultrawide HiDPI #3674

Hi,

another "Vision Pro - Ultrawide" observation. When I add virtual display with mirror / stream option I get crystal clear resolution with possibility of full screen zooming, and having high resolution even, when zoomed-in. This allows me to use 2x4K (7000+ width resolution) and zoom in to part of screen if necessary.

BUT

I found, that performance of stream to Vision Pro is poor (every few seconds screen is chopping, watching YouTube is terrible etc.). But I found solution - you just need to use system full-screen zoom and zoom in a little bit (like 1%), and it's working completely smoothly.

I found also, that enabling software display adjustments with metal and decreasing brightness by 1% do almost similar job (chopping is much less visible).

I don't know if this problem existed before latest macOS beta's and whole ultra-wide condition, but it looks like system zoom is doing something with stream / rendering (disabling some optimization?).

If you have any idea how to address it, and/or solve I would love to hear that. I can exclusively help you with testing features for Vision Pro streaming, if you need. Thank you!
