Perfect frames is what Mac and Windows provide and what Linux should also aim for. Border tearing is a display bug, correctness should come first, Wayland's approach is right. X was designed for CPU and IO constraints that no longer apply. _Graceful_ degradation of slow UI should lower the frame rate, not compromise rendering of individual frames.

> Perfect frames is what ... Windows provide

Citation needed. Windows has its own share of graphics bugs, even on "corporate" hardware (HP).

		Well, exactly. Windows does try to provide perfect frames. If the display glitches, it's considered as bug rather than the momentarily acceptable degradation that OP was praising X for.
