We have been using this for years now and did not observe issues you mentioned. I would be surprised if a child window refreshes in a different rate than the main window Am 13.07.2016 11:44 schrieb "Michel Dänzer" michel@daenzer.net:

Whatever action is taken, it is fine for Kodi. GLX+OML_sync_control is not an option anymore because we need EGL for vaapi. But we can fall back to the invisible window for getting vsync. I never tried using EGL and GLX in the same application, different windows. Any reason why this should not work?
An invisible window may not synchronize with the same output refresh cycle as your output window.
