As you say, purely software rendering was almost certainly infeasible to scale as resolution and refresh rates went up, but we've had at least a decade of having stupidly powerful 2D GPU hardware in all our shit.
Bring back my stupid Compiz effects. They were fun, and sometimes genuinely useful.
Cosmic has sexy transparency effects but God the color schemes are so poorly thought through.
Out of the box their light terminal theme is flat out unreadable. Some of the chosen colors have almost no contrast.
Ugh.
And then if it is dark mode time but I pull up a terminal window that is semi transparent and it is on top of a browser window that has bright colors, again, unreadable.
Which is why transparency effects are mostly limited to cool screenshots.

sir, this is not an agentic window
KDE / kwin has wobbly windows
