This issue has been verified using Visual Studio 17.11.0 Preview 2.1 (8.0.40 & 8.0.60). Can't be reproduced on windows platform. When I set the ratio to greater than 100%, the CollectionView still displays normally.

Could you please provide the code snippet you're working with?

Sample - https://github.com/gauravK996/Sample/blob/main/CollectionViewDemos.zip

=> Click on vertical grid

span set to 3 but it shows only 2 item in a row

maximizing or changing window size also flickers item numbers in a rows.

MAUI Version - 8.0.61 SR6.1 (Last version that worked well - 8.0.7)

My recommended settings for size 100%, but you can try with different sizes.

Removing this dpi settings from platforms=>windows=> app.manifest will temporarily fix this problem.
