Option to disable rounded corners?

The new rounded corners on everything is terrible. Is there an option to go back to the unrounded?

MacBook Air 13″, macOS 26.5


And just now it is an issue(?) Tahoe was released in Sept 2025...


Yes macOS Tahoe introduces dramatically larger, highly controversial rounded corners for application windows as part of its new "Liquid Glass" design— you have limited options for making changes to the interface— note the rounded corners are not one of them.


The current stable release of Tahoe including bug fixes, security updates is macOS 26.7
