It's a giant "fuck you" to accessibility in general. It reminds me of the first designer I ever worked with, who designed for pretty screenshots and put zero thought into the actual interaction.

E.g. the pervasive use of transparency means that you have text overlayed on text all over the place, so just literally can't read things.

It's not just the transparency (and distracting highlights and slow animations and inexpressive icons), but also the floating controls and other elements that make it harder to discern what is content and what is UI chrome/controls, not to mention the associated layout bugs.

Turning transparency off significantly improves the look and responsiveness imo.
