Nico, are you aware that stransky is actively working on bug 788319 (or bug 1640048 as first step) as it's needed for bug 1619523? I don't think it makes sense to invest much time into the GLX backend - the EGL backend gives us partial damage in a proper manner for free (as it's shared with Wayland/Android).

Edit: most importantly bug 1580166 has already landed - it's necessary to get good WebGL performance without readbacks)

Edit2: that means with bug 1640048 applied you should already get partial damage support when using the nvidia proprietary driver. Mesa drivers are blocked by https://gitlab.freedesktop.org/mesa/mesa/-/issues/3030

edit3: also, `glxCopySubBufferMESA` is obviously not supported on the nvidia driver - and mesa drivers benefit the most from the switch to EGL because of the dmabuf work.
