PC | Input delay & Menu sounds during the game after last patch

After the latest patch, you can hear the sound of buttons and menu movements in matches, and when that noise occurs (9 out of 10 matches), the match has noticeable input lag.
IMPORTANT: It's not due to the fire and ice aesthetics on cards. I used an all-gold team against an identical opponent and I'm having the same problem. This problem appeared after last Friday's patch.
