Hi folks, XQuartz is the only DDX using miext/rootless. This code doesn't play well with modern X servers. For example, it is incompatible with COMPOSITE (cf https://gitlab.freedesktop.org/xorg/xserver/-/issues/1409), other rootless DDXs (eg: xwin, xwayland) don't make use of it, and we carry some hacks to miPaintWindow() in XQuartz that are too messy to upstream just to get it to work.
I'd like to remove miext/rootless. Specifically, I want to move it into hw/xquartz and begin code-folding it away. Is there anyone that sees any value in keeping the miext/rootless generic support around?
