> As someone who is working with X11, I strongly disagree. It really needs replacing badly. It doesn't even work; only a few code paths even get tested on for example GLX, which is why complex X11 apps like browsers need blacklists.

Blacklists are needed because OpenGL drivers for specific hardware have bugs and can have missing functionality. Those can affect Wayland too, since the same drivers are used.

Modern Xorg supports direct rendering well, Keith Packard authored a lot of modernized infrastructure such as DRI2/DRI3, and even support for VR (work he's been doing for Valve).

There's also the important VK_display_timing extension implementation he's done with Croateams Alen Ladavac:

Sadly, I don't see much more recent activity from him or Alen about these topics, but it shows that Xorg is still the main platform of inovation for Linux real-time graphics needs.
