Path 1.07 dropped today which claims to fix some graphical issues. To be fair; I've not noticed the shimmering issue when playing on performance mode.
Thanks, I checked and it's still prevalent. Apparently exasperated for OLED's due to some techy reason I don't understand so won't bother quoting

Edit: Oops, hadn't actually updated. According to what I read though, those issues are still being investigated. Hopefully soon.
