A naïve synchronization within dri2_wait_x.

Seems to workaround the issue.

Note, that Firefox also encountered issues with the X/GL synchronization [1].
They went to use XSync directly.

Additionally, could one extend 95073a2d with something like
-   if (ctx->Driver.Viewport) {
+   if (ctx->Driver.Viewport && (ctx->NewState & _NEW_VIEWPORT)) {
? At least doesn't blow up my machine...
