Hi @taghisouf, thanks for the good info. I am having a look as well and am working to reproduce the broken perspective behavior in current chrome version and help to get this reported.
Edit
As the creator of the video also has posted on their YouTube channel, there is an issue with chrome 93 + with the perspective reported as a chromium bug, the Webflow team is aware of the problem and the issue already with our team and I expect an update to be forthcoming for this.
I do not have the exact timeline of the update, but I will help to share that here when I know an update has been made.
If you wish to view the original bug report for chromium on this issue: 1247884 - chromium - An open-source project to help move the web forward. - Monorail
Also feel free to follow this post regarding the same issue: Changed behavior of perspective(0) in Chrome 93
Thanks for sharing that info
