<pre>I have some XCB OpenGL code which, in the meantime until I port it to Wayland,
I would like to be able to use under Xwayland.
I use the OML_sync_control extension to discover refresh rate (with
glXGetMscRateOML()) and I use glXSwapBuffersMscOML() instead of
glXSwapBuffers(). Unfortunately, neither of these functions seem to work under
XWayland 1.16.1. The Xwayland window shows up black, but when I switch back to
glXSwapBuffers(), rendering and display proceeds as expected.
I am also getting garbage results from glXGetMscRateOML(). Under Xorg on this
machine, I get a (numerator, denominator) pair of (687500, 11457) (~60.006hz).
Under XWayland, I get a variety of numerators and denominators, none of which
are close to 60hz. Several samples of the return values I get are (1,
22259776), (1, 11782208), (1, 9910336), and (1, 22751296).</pre>
