Lag only in full screen mode

[shantanu saha]

Audience has lag issue when run in full screen mode. Video quality is 720p & 1080p. There is no lag in normal mode (window).
I have checked using Nvidia and Intel driver. In both situation I got the same result.

System info:
Intel Core i7
Nvidia 740M
Intel 4600 GPU
