I gather from this that X11 will be completely unaffected? Wanting to depend on unreleased software is unprecedented for a component of kde-workspace providing a commonly expected feature - and is something I find objectionable. Especially if the dependency offers no benefits to those of us whom recieve no benefit from the increase in dependencies. > > It should not affect the runtime requirements for X11, but if Mesa 7.11 gets > released before our 4.8 dependency freeze, we have to depend on it. Can you please clarify what you mean by we *have* to depend on it? Does this mean which of the following: * CMake level check making KWin completely unavailable to people without Mesa 7.11 * Runtime level check making all compositing unavailable to people without Mesa 7.11 - regardless of whether it is X or Wayland * Runtime level check only concerning Wayland Either of options 1 and 2 are completely unacceptable under any circumstances - considering that people who will be developing for 4.8 will be doing so under distributions which ship 4.7 - which will probably only have Mesa 7.10. Compositing alters the way the window system operates and can expose bugs - and by imposing these dependencies you are inhibiting the ability of other developers to triage and fix bugs or other defects. > > Cheers > Martin > Regards, Ben
