Same here and with latest mesa.

The following hack/workaround also fixes the problem:

diff --git a/src/glx/dri2_glx.c b/src/glx/dri2_glx.c
index d6eb281..28b8de4 100644
--- a/src/glx/dri2_glx.c
+++ b/src/glx/dri2_glx.c
@@ -853,7 +853,7 @@ dri2SwapBuffers(__GLXDRIdrawable *pdraw, int64_t
target_msc, int64_t divisor,
     }

     /* Old servers don't send invalidate events */
-    if (!pdp->invalidateAvailable)
+    if (1 || !pdp->invalidateAvailable)
        dri2InvalidateBuffers(dpyPriv->dpy, pdraw->xDrawable);

     return ret;


But looking at the reason why it is working in the egl case, I found this
commit:

    egl: Restore "bogus" DRI2 invalidate event code.

So I guess one could do something similar than egl, i.e. for glx, having
"pdp->invalidateAvailable" equals to false in more cases.
