Queue / Accept match bug

This has been happening a lot more recently to the point that it just happened to me back to back in 2 games. I will be in queue, get a game pop and accept, alt tab to whatever else I'm doing and then hear the sound keep playing out (this happens regardless of tabbing out, I'm just describing the situation). I then alt tab back in, to find the accept and decline button unclickable on a black background. Upon closing and reopening the client, it will give me a dodge penalty despite not actually joining the lobby. This has happened 3 times today so far, losing me lp and a 30 minute timer. This has been a long term bug for the new client (not so new anymore, kind of confusing to me) but recently has picked up frequency. I play on OCE, alot of my friends have been having this similar issue. I know it's preseason but I still enjoy playing in a more tryhard environment than resorting to norms. I feel as though this particular problem has been asked about countless times by many people with no legitimate response other than some PR stuff like "we're working on it". Working on what? The new client remains a buggy mess with a pretty face. The old client may have been less aesthetic pleasing and intuitive but at least it was functional.
