In addition: Win 8.1 Opera 49.0.2725.47 icon on the push not displayed http://prntscr.com/hge2i7
Improvement. May be it'll be better to open new tab after click on push instead opening new opera window? Or this parameter can be changed somewhere?
@sgunhouse Yes, that's it. It's more of a progressive thing however, if I am watching it the audio isn't out of sync with the film/tv show to begin with, but it slowly becomes out of sync, refreshing the page fixes that but only for a short while. I have only recently started using Opera, so I am unsure whether this could be due to an option that I could select in order to stop this from happening.
