Vk.com, playing music causing scratching/jump in the middle of song

[voidex]

When playing playlist on vk.com, there are scratch (jumping back on ~100ms 2-3 times) in some point of music. Usually near middle. Seems, that it's not vk's issue as long as i coudln't reproduce it with Edge. ----- Vivaldi 1.4.589.38 (Stable channel) (32 бит) Версия afa9b018e32575fcd8f8283755a315804ecf0671 ОС Windows // 10, x64 Blink 537.36 (@afa9b018e32575fcd8f8283755a315804ecf0671) JavaScript V8 5.3.332.47 Flash 23.0.0.185
