We should fence  the texture to render in its internal GL context, and wait  for its rendering in our application GL context, otherwise the GL pipeline could be working on the texture when painting it.
Well, I guess this enhancement doesn't make much sense since it uses OpenGL API 3.5 while webkitgtk uses 3.0
Could this be useful for WPE though?
For EGL there's an equiivalent but it doesn't seem to be supported in GStreamer:

If I understand correctly, at least in i915, the implementation is the same for both
And in another spec I read that the glFenceSync spec is newer, thus it is expected to cover the EGL usage.
Reopening because it's required for other context, specially on EGL.
