Hi Scott, were you thinking to make
https://cgit.freedesktop.org/mesa/mesa/tree/src/glx/dri2_glx.c use more
xcb_dri2_* calls ?

Currently it uses a mix, for example it calls "DRI2Connect" but also calls
"xcb_dri2_swap_buffers"

The remaining DRI2 calls are:
DRI2Connect
DRI2Authenticate
DRI2CreateDrawable
DRI2DestroyDrawable
DRI2CopyRegion
DRI2GetBuffersWithFormat
DRI2QueryExtension
DRI2QueryVersion

Looks like
https://cgit.freedesktop.org/mesa/mesa/tree/src/egl/drivers/dri2/platform_x11.c#n612
is a good example for this conversion. Also some refactoring can be done to
share the code between mesa/src/glx/dri2_glx.c and
mesa/src/egl/drivers/dri2/platform_x11.c

But why it will solve the fact that currently
mesa/src/glx/dri2.c::DRI2WireToEvent::dri2InvalidateBuffers is not called when
the app owns the event queue ?
