I thought that XWayland did not support OpenGL contexts.
That it could only be used for application software.
"The main use of DRI is to provide hardware acceleration for the Mesa implementation of OpenGL."

It would be nice, if XWayland could be used with the Nvidia blob - simmilar like Bumblebee.

The performance "overhead" of xwayland is pretty much non existent. On X we do unredirect games so they do run uncompisted means that they run faster.
I do have patches for mutter to do the same on wayland (weston already does this btw.) but they didn't get finished in time for 3.14.
Fantastic. Thank you for this info.

Wrong conclusion
The performance overhead of running on a Wayland session and going through XWayland for these older OpenGL applications is still very noticeable.
