>Using X11? Sure, I love display servers that choke on high DPI and cannot do half the things modern compositors do efficiently.

X11 has XRender since ages. Now it has XCB and optimized setups.

And, OFC, composited Window Managers avoiding raw X11 calls with X11 extensions... since early 2000's.

Still doesn't do well with high DPI (most phone screens go around 500dpi), still doesn't do well with high refresh rates, etc.

Using X11 for any modern needs is an aberration.
